Beginner tips for PHP master


PHP is the language behind the absolute most dominant and inescapable web applications around, including the omnipresent Facebook and the relentless WordPress. Learning another dialect can be overwhelming, so we've tapped a couple PHP experts for their guidance for tenderfoot php development coders (stay tuned for a transitional/propelled determination of tips, coming up in two or three weeks).

In case you're another PHP developer (or an old professional), make certain to leave a note in the remarks and let us and different readers realize what explicit advances you've taken that is made learning the language simpler for you.

Go for object oriented programming

Naramore is a SourceForge worker and established PHPWomen.org. For complete beginners, she suggests getting an intensive foundation in item situated programming (OO) before jumping straight into PHP.

"In case you're originating from a non-tech industry, set aside the effort to learn strong standards of programming advancement. Things like item arranged programming, test driven advancement, adaptation control, troubleshooting, structure designs, and so forth.

Procedural Programming works by following an everyday practice from the top to the base of each page as the server peruses each record on your server. With OOP, there could be a couple of items being instantiated, which, thusly could instantiate a couple of, a hundred or a thousand different articles which could all play out specific errands relying upon factors go into the articles. OOP is quicker, less complex, simpler to investigate, utilizes less server assets, less code, is quicker stacking and progressively coherent to work with once you make sense of the essential standards.

Maintain distance from the code end with _once()

We all realize that include() just gives us a notice on the off chance that it comes up short, while require() kills the script with a lethal mistake when it falls flat. What we remember is that include_once() and require_once() is very hard on server resources. There is nothing we can do about it, it's the manner by which PHP is set up.

Develop with reporting error on

The first thing you do when beginning another undertaking is to turn blunder answering to E_ALL, and you should just turn it off ten seconds before going to generation mode. I do this with each venture that I manufacture and there is nothing superior to running an undertaking in full generation mode and not in any case getting one mistake. Other than that, with mistake giving an account of, you get any little blunders that will inevitably grow up to chomp you in the... all things considered.

Use a structure if needed

Structures that help you do the dreary things can help, despite the fact that you should figure out how the structures work first so as to make things basic, yet that is the main genuine exchange off. Additionally, you stand less shot of composing awful code when another person has composed the greater part of it for you, yet how about we imagine I didn't state that.

Use inbuilt functions of PHP

Alright, you need to include the measure of keys in a cluster? You can circle through the cluster and essentially increase an incentive for every emphasis, isn't that so? Or then again you can simply utilize the implicit PHP function count(), which does exactly what it should. PHP has many worked in capacities that can do what you need them to, so look at the manual to ensure you are doing it in the most ideal manner possible.

Database protection

The best and most secure path is to utilize mysql_real_escape_string() for all database before it is added to the database. This capacity makes all strings secure as far as statements and other different capacities that can hurt your database or contain malevolent code, so use it to make certain you have ventured out assurance of your information. Something else you can do is approved all POST and GET strings, never use $_REQUEST, and ensure all structure submitted information is of the correct kind and incentive before adding it to a database question.

Draw before you code

A decent practice to get into is to wireframe your projects, regardless of whether you are simply writing a couple of notes on a bit of paper. It is imperative to really give the mechanics of your application some idea before plunking down to begin coding, on the grounds that during the time spent arranging it you will really iron out the troubles in your mind and keep away from the real cerebral pain that accompanies the facepalm when you understand that all that you simply did is either wrong, not required, or very easy senseless.

Understand the project


An artist can't draw something that he has not seen previously. An artist can't sing a tune that he has not heard previously. You can't code a venture that you don't completely get it. On the off chance that you don't see precisely what it needs to do, and how it needs to it, you can't manufacture it.

Top Amazing tips and techniques to develop a mobile web apps


As a mobile device user, few things square measure as frustrating and troublesome to fat-finger-navigate as a poorly designed mobile web app, or maybe a native app.

And as a mobile app developer, few things are most as intensely irritating and frustrating as strain to support as wide a spread of mobile purchasers as potential, each of which has its own frustrating set of idiosyncrasies. Like mobile device user, few things are as frustrating and damn difficult to fat-finger-navigate as a poorly designed mobile web or native app either. And as a mobile app developer, few things can be as intensely irritating as striving to support as broad a range of mobile clients as possible, each of which has its own self frustrating set of idiosyncrasies.

There are already many tools which we can talk about for ipad website development and web design and web development on your iPad. Apps that allow us to create so many color schemes, retouch images and also write and work with CSS3, create your own fonts and techniques in minutes, create apps for iPhone and iPod, etc..

Mobile Web App vs. Native App vs. Hybrid App
As is true with most technology choices, there’s no one-size-fits-all answer when it comes to the type of mobile app to develop. There square measure various internet app best practices to contemplate, not all of which are technical. Who is your target audience?

Mobile Web App Development Requires Detailed Planning
Identifying your (or your customer’s) necessities is one among the most essential best practices in app development, mobile or otherwise. Carefully research the targeted capabilities to see if they are realizable in your mobile internet app.

Remember to verify before that the functionality you’re trying to find is supported across the device landscape that your customers square measure possible to be exploitation.

Optimizing Your Mobile Web Application for Performance
You must thus consider carefully regarding the way to scale back and optimize each computer memory unit and server transfer to cut back the user’s wait time. It’s unrealistic to expect that transfers will always be done over a WiFi network, and you should know that 60% of mobile web users say they expect a site to load on their portable in 3 seconds or less (source). Similarly, Google found that, for every extra five seconds of load time, traffic dropped by 20% Image Optimization. Image load time is well-known to be one among the biggest performance issues moving page load on mobile devices. Use of online image optimizers, such as smushit.com and many other, can be helpful in addressing this issue.

Code compression.

Compressing your JavaScript and CSS files, depending on the amount of code you have, can potentially and succeedingly have a significant impact on performance.

Database queries.
Some mobile device browsers don’t accept as many cookies as desktop browsers do, which might end in the requirement to execute even a lot of queries than usual. Server-side caching is thus especially crucial when supporting mobile net app shoppers.

Content delivery networks (CDN).
If you are progressing to offer millions of videos, images, audio files, or other types of media, use of a CDN is highly recommended. Some of the more common commercial CDNs embrace Amazon S3, Microsoft Windows Azure, and MaxCDN. The advantages of using a CDN square measure

varied and include:
Improved download performance. Leveraging a CDN’s resources makes you to distribute load, save bandwidth, and boosts performance. The better CDNs provide higher accessibility, lower network latency, and lower packet loss.

Mobile Web App Development Tools
“The right tools for the proper job” is an old saw that applies as much to software system development because it will to any other domain. This tutorial provides and introduction to some of the more popular and widely-used tools for mobile web app development, but bear in mind that there may very well be other tools that square measure the “right” ones for developing your mobile web application, depending on your needs and on the market resources.

Choosing the Right JavaScript Mobile Web App Framework
As mobile web app development tend to make several of an equivalent common challenges – such as cross-browser compatibility and inconsistent hypertext mark-up language and CSS in mobile browsers – frameworks have been developed (based on HTML5 and CSS3) that are specifically designed to address these issues and to work as flawlessly as possible on a wide array of smart phones and tablets.

Look and feel. 
Generally speaking, the planning and feel of a Sencha touch app is crisper and superior to it of a jQuery mobile app, but it's necessary to recollect that such reactions do tend to be highly subjective.

Extensibility.
Query Mobile offers a lot of third party extensions and is inherently designed to be highly protractile, whereas Sencha touch is currently way more of a “closed” framework.

Device support.
Query Mobile currently targets a larger cross-section of devices than Sencha bit.

HTML “vs.” JavaScript. jQuery is largely HTML-centric (i.e., extending and manipulating existing HTML in JavaScript), whereas Sencha Touch coding is entirely JavaScript-based. Responsive Frameworks and Mobile Web

Applications
An increasing high range of responsive frameworks have just begun cropping up in recent years, with two of the currently most popular being

Bootstrap and Foundation.
It is mostly based on CSS and JavaScript, many of these frameworks are an open-source, free to download, and easily customizable.

Many factors should be thought-about once choosing between web, native, and hybrid mobile app options for mobile devices. Each has its own advantages, however mobile web apps can usually represent your most efficient development (and thus time-to-market) choice. Should you choose to go down that path, I hope this mobile web app development tutorial helps get you more directly and successfully to your destination.

5 Major Advantages of Using MySQL

Utilizing PHP, yet at the same time don't have the foggiest idea how MySQL can help you in your various Web Development projects? Peruse on and get illuminated. MySQL is one of only a handful couple of open-source common database management systems. The 'My' is added from the name of founder Michael Widenius' girl, and the SQL means 'Structure Query Language.' While practically all PHP developers realize that MySQL is quickly turning into an essential part in web development all over the place, relatively few have completely comprehended the thought of the combined effects of MySQL and PHP. In any case, that is the place we come in. We will highlight its various advantages and help you decide an ideal approach to use the PHP language.

1. Support

MySQL merely is one more essential language like PHP, and then consolidated for a web development task, they can make shocking websites. They give considerably more effective outcomes than sites built on the base of just a single language, and PHP developers can utilize this innovation to create something uncommon each time. Websites with MySQL as the background database notwithstanding, are only one case of how the two languages support one another and make programming fun and simple.

2. Creating Dynamic Sites

As has been referenced above, both PHP and MySQL can work amazingly in a community development condition. PHP is currently considered a standout amongst the best server-side languages, and MySQL is utilized alongside it to empower programmers to make sure and solid frameworks for web development systems. This is the reason it is moderately simple to use the two databases in the WordPress precisely as proposed by the developer.

A dynamic website made with the assistance of PHP and MySQL makes the PHP developer's activity simpler than any time in recent memory since it can undoubtedly be changed, controlled and refreshed. While PHP can be embedded into HTML or any language used to create website pages, MySQL can be utilized as a database that works out of sight and essentially offers help.

3. Cost

A standout amongst the most successive issues looked in web development is unexpected expenses. To begin with, you can't consider setting up a website without spending on name enrollment, which opens up a veritable Pandora's Box. You will at that point need to deal with facilitating and its various types, just as the expenses incurred on programming and development-related tricks, also the sum that you will pay to a good PHP developer.

Presently, to make your website considerably progressively dynamic, you can utilize MySQL. Developers love the blend of PHP and MySQL because it is very cost effective, requires low-end equipment and less problem.

4. Trustworthiness, Ease and Open Source


The best thing about the PHP and MySQL combo is its honesty, ease, and their open-source properties. PHP developers lean toward not revamping every single line of HTML in an outsider like a programming language. This is because PHP is a WYSIWYG language and it very well may be altered by WYSIWYG editors, which makes it simple to change. These astonishing customizable options again make it simple for PHP developers to create exceptional and dazzling websites, including web-based business websites.

CHALLENGES OF SCALING MYSQL

Scaling frameworks that can't be streamlined with ace/slave setups requires full development time. Replication lag further muddles application rationale since it disturbs the information consistency between the slave and the ace. At long last, MySQL server adjustments need steady coordination between database groups and applications.

Replication

MySQL servers regularly keep running into replication clashes amid a manual failover when multi-ace setups are included.

Database Logging Costs

Database logging is costly; thus it stays crippled more often than not. Therefore, associations need ongoing permeability into moderate logs, which delays investigating.

Query Caches


MySQL server query reserve is of little help when dealing with a high volume of workload since store nullification can't be controlled.

High Connection Churn


If your applications depend on a LAMP stack, they will, in general, have a high volume of user sessions running simultaneously and, like this, they experience a high association beat. So the more significant part of your essential server resources is depleted on association management.

A few organizations consider sharding as a scaling choice, yet sharding includes critical multifaceted nature, cost and its very own arrangement of other difficulties. The least demanding approach to use the ground-breaking highlights of MySQL without making any adjustments at the application level or composing a single line of code is to use database load balancing programming.

The Solution? Database Load Balancing Software for MySQL

Database load balancing programming unravels the difficulties that crop up when scaling your MySQL database. It empowers programmed to read/to compose split so you can use readable replicas with no code changes, enlarges failover to make it undetectable at the user or application level, gives unparalleled permeability into analytics, and encourages a single tick straightforward reserving. This natural, agentless methodology builds reaction times up to 60X, averts downtime amid database failovers, duplicates website execution and guarantees better business results. With database load balancing programming, undertakings can overhaul their applications in a moment and ensure that they stay ready for action around the year.

Since the HTML5 web development is still work in progress, many think that this is not the best solution or a new translation the need for the companies web development.

HTML5 gives access to high-level functions which make makes the most used for the web development and is already seen across all the websites whether the device is a mobile or a laptop or just any other screen. This latest version of HTML is used to create websites that are accessible for the semantics and AIRA features provided by HTML5.

Through this article, letters have a look of those best reasons that make HTML5 to be the technology for web development. You can also hire html5 developer for the work.

  • HTML5 is the best solution to develop various mobile apps and mobile websites because it provides various readymade and easy features to develop and provide the application regarding mobile development pretty easily. Is taking over the world the laptops or the computers may be outdated but mobile is definitely the future of technology, and hence the mobile app development would be pretty much needed and HTML5 provides ready to use features, and it is the future.

4 Things You Should Be Check Now To Improve Php Web Development

PHP: Hypertext Preprocessor or simply PHP is a scripting language or programming language concocted by Rasmus Lerdorf in 1995. At the initial stage "Personal Home Page" was the acronym for PHP web development application. It was planned for the personal use of the developer but later when its functionality increased the named changed to "PHP: Hypertext Preprocessor".


From the beginning, PHP has become one of the most well-known programming languages for Web development applications. There are many popular websites which are powered by PHP as well as the majority of scripts and Web projects are also developed with the help of PHP.|

Know the right time to begin optimizing PHP:


You should first run benchmarks on your hardware as well as software in order to determine the performance parameters. It will help you understand the risks and benefits of specific trade-offs thus will guide your coding. Use adequate test data to create code that scales.

Here are 4 excellent tips that will surely help PHP developers to increase or speed up the up the performance of the PHP web development application. Every PHP web developers should learn and follow these basic tips whenever they program.

1.    Upgrading your PHP to the latest version:

If you are using the old versions of PHP web development application then you are surely missing a lot of new features and improvements related to the performance that has been made to the application. Every new version of the PHP web development application has something new compared to the previous versions.

In case you are working with legacy code then upgrading to the new versions of PHP web development is not always a simple task! In any case, if the application is experiencing any performance issues then updating the application to the latest version is the best task that one can follow.

With the release of every PHP updates, there is an increase in performance associated. The performance increases roughly to 100 percent across all kinds of applications.  Not upgrading to the newest version is an indiscreet decision one will make in terms of performance point of view. Upgrading to the newest version will result in less memory consumption which enables you to handle many requests at the same time without depleting the memory of the server.

2.    Take the advantage of using an accelerator such as APC or OPCache:

 In two steps PHP runs your code and they are:

●    PHP compiler will transform the script from PHP code into opcodes
●    Then the PHP virtual machine will execute this intermediate cache format.

 The first step of this process can be cached by the accelerators such as APC or OPCache until the PHP file changes.  An accelerator can double the performance. This ability of an accelerator depends on the kind of application you run and the PHP version is used by you. Latest versions of PHP include OPCache so that's why it is advisable to upgrade to newer versions.

In case if you are running the application on shared hosting then there is a chance of having a disabled opcode cache. The hoster may disable this opcode cache for security reasons. You can move your code to the modern hosters that provide you with the control and are pretty much affordable. You can use Digitalocean and Syseleven for hosting.

3.    Distinguish the delays in the database and neaten your filesystem:


The code doesn't cause the performance problems always.  When the application accesses the resources then most of the congestions occur & this results in lowering the performance of the application. You should look at all the occurrences of database access in code access. This should be done as the data access layer of a PHP web development application is responsible for the occurrence of 90 percent of execution time.

In order to identify and address slow SQL queries turn on slow SQL logs. After that check their efficiency by querying the queries. You can cut down the database access time to boost your application's performance. This can be done if. If there are many queries are being made or same queries are being made several times during a single execution.

You should remove your filesystem if there is any inefficiency present. You should also ensure that the filesystem isn't being utilized for session storage. Look out for codes such as file_exists(), filesize() or filetime() which can trigger a file stat. If any of these functions are present then there will be issues related to performance.

4.    Use XDebug and monitor the APIs:

You should profile your PHP to manage the external resources as a full PHP code profile supplies you with in-depth information about the performance of your application. You can use XDebug to profile your PHP code. Most web applications depend on remote APIs. You can eliminate the problems resulting from AP by establishing timeouts for API requests.

How to Upload Files Into a MySQL Database Using PHP?


MYSQL is utilized for creating database for websites and web applications. With its amazing performance, dependability and usability, MySQL has become best database option for web applications. It is freely accessible and simple to install. When the user uploads a file and tap on the upload button, the data is submitted to the server. PHP now takes the file and saves it in a folder in the project. Afterwards, it saves the text in the database together with a link pointing to the image in the folder. Now the biggest question is that how to upload files to MySQL database using PHP? Let’s learn.

Phase 0: Creating A Database
The process of creating database is easy. One table with a Binary large object (BLOB) field for the file data and some fields for different pieces of information relating to the file:

1. CREATE TABLE `file` (
2. `id` Int Unsigned Not Null Auto_Increment,
3. `name` VarChar(255) Not Null Default Untitled.txt,
4. `mime` VarChar(50) Not Null Default text/plain,
5. `size` BigInt Unsigned Not Null Default 0,
6. `data` MediumBlob Not Null,
7. `created` DateTime Not Null,
8. PRIMARY KEY (`id`)
9. )
10.

As you see, a file is stored by their, including the extension. We have the mime type, which is used to let the browser know what kinds of file are dealing with. us The size of the file in bytes. And finally the data itself, in a MediumBlob field.


Phase 1: Uploading The File
Now, there is need to get the file from the user. The table we designed does not want further information from the user. So, we will make this easy and create a HTML form with only a single "file" input field and a submit button:

1. <!DOCTYPE html>
2. <head>
3. <title>MySQL file upload example</title>
4. <meta http-equiv="content-type" content="text/html; charset=UTF-8">
5. </head>
6. <body>
7. <form action="add_file.php" method="post" enctype="multipart/ form-data">
8. <input type="file" name="uploaded_file"><br>
9. <input type="submit" value="Upload file">
10. </form>
11. <p>
12. <a href="list_files.php">See all files</a>
13. </p>
14.</body>
15.</html>
Now look at the above mentioned code and you can see the third attribute of the <form> element, "enctype". This tells the browser how to send the form data to the server. As it is, when sending files, this require to be set to "multipart/form-data".
In the event that it is set any other way, or not set at all, your file is presumably not going to be transmitted accurately.

Phase 2: Add The File To The Database
As you can see in phase 1, we set the action property to "add_file.php". This is the file we are going to build it this phase of the process.

This file needs to check if a file has been uploaded, ensure that it was uploaded without errors, and add it to the database:

1. <?php
2. // Check if a file has been uploaded
3. if(isset($_FILES[uploaded_file])) {
4. // Make sure the file was sent without errors
5. if($_FILES[uploaded_file][error] == 0) {
6. // Connect to the database
7. $dbLink = new mysqli(127.0.0.1, user, pwd, myTable);
8. if(mysqli_connect_errno()) {
9. die("MySQL connection failed: ". mysqli_connect_error());
10. }
11.
12. // Gather all required data
13. $name = $dbLink->real_escape_string($_FILES[uploaded_file] [name]);
14. $mime = $dbLink->real_escape_string($_FILES[uploaded_file] [type]);
15.$data=$dbLink->real_escape_string(file_get_contents($_FILES [uploaded_file][tmp_name]));
16. $size = intval($_FILES[uploaded_file][size]);
17.
18. // Create the SQL query
19. $query = "
20. INSERT INTO `file` (
21. `name`, `mime`, `size`, `data`, `created`
22. )
23. VALUES (
24. {$name}, {$mime}, {$size}, {$data}, NOW()
25. )";
26.
27. // Execute the query
28. $result = $dbLink->query($query);
29.
30. // Check if it was successful
31. if($result) {
32. echo Success! Your file was successfully added!;
33. }
34. else {
35. echo Error! Failed to insert the file

37. }
38. }
39. else {
40. echo An error occurred while the file was being uploaded.
41. . Error code: . intval($_FILES[uploaded_file] [error]);
42. }
43.
44. // Close the mysql connection
45. $dbLink->close();
46. }Now, using this summary as a guide, lets start writing our program.

Phase 3: Listing All Existing Files
So, now that here is few of files in our database, we have to make a list of files and link them so they can be downloaded:

1. <?php
2. // Connect to the database
3. $dbLink = new mysqli(127.0.0.1, user, pwd, myTable);
4. if(mysqli_connect_errno()) {
5. die("MySQL connection failed: ". mysqli_connect_error());
6. }
7.
8. // Query for a list of all existing files
9. $sql = SELECT `id`, `name`, `mime`, `size`, `created` FROM `file `;
10.$result = $dbLink->query($sql);
11.
12.// Check if it was successful
13.if($result) {
14. // Make sure there are some files in there
15. if($result->num_rows == 0) {
16. echo <p>There are no files in the database</p>;
17. }
18. else {
19. // Print the top of a table
20. echo <table width="100%">
21. <tr>
22. <td><b>Name</b></td>
23. <td><b>Mime</b></td>
24. <td><b>Size (bytes)</b></td>
25. <td><b>Created</b></td>
26. <td><b>&nbsp;</b></td>
27. </tr>;
28.
29. // Print each file
30. while($row = $result->fetch_assoc()) {
31. echo "
32. <tr>
33. <td>{$row[name]}</td>
34. <td>{$row[mime]}</td>
35. <td>{$row[size]}</td>
36. <td>{$row[created]}</td>
37. <td><a href=get_file.php? id={$row[id]}>Download</a></td>
38. </tr>";
39. }
40.
41. // Close table
42. echo </table>;
43. }
44.
45. // Free the result
46. $result->free();
47.}
48.else
49.{
50. echo Error! SQL query failed:;
51. echo "<pre>{$dbLink->error}</pre>";
52.}
53.
54.// Close the mysql connection
55.$dbLink->close();
56.?>

Phase 4: Downloading A File
To truly see how this functions, you should see how your browser downloads documents. When a browser asks for a file from an HTTP server, the server reaction will incorporate information on what precisely it contains. These bits of information are called headers. The headers ordinarily incorporate information on the sort of data being sent, the size of the reaction, and in case of files, the name of the file.

Now, this code. We begin simply by reading the ID sent by the link in phase 3. If the ID is valid, we fetch the information on the file whose ID we received, send the headers, and finally send the file data:

1. <?php
2. // Make sure an ID was passed
3. if(isset($_GET[id])) {
4. // Get the ID
5. $id = intval($_GET[id]);
6.
7. // Make sure the ID is in fact a valid ID
8. if($id <= 0) {
9. die(The ID is invalid!);
10. }
11. else {
12. // Connect to the database
13. $dbLink = new mysqli(127.0.0.1, user, pwd, myTable );
14. if(mysqli_connect_errno()) {
15. die("MySQL connection failed: ". mysqli_connect_error ());
16. }
17.
18. // Fetch the file information
19. $query = "
20. SELECT `mime`, `name`, `size`, `data`
21. FROM `file`
22. WHERE `id` = {$id}";
23. $result = $dbLink->query($query);
24.
25. if($result) {
26. // Make sure the result is valid
27. if($result->num_rows == 1) {
28. // Get the row
29. $row = mysqli_fetch_assoc($result);
30.
31. // Print headers
32. header("Content-Type: ". $row[mime]);
33. header("Content-Length: ". $row[size]);
34. header("Content-Disposition: attachment; filename =". $row[name]);
35.
36. // Print data
37. echo $row[data];
38. }
39. else {
40. echo Error! No image exists with that ID.;
41. }
42.
43. // Free the mysqli resources
44. @mysqli_free_result($result);
45. }
46. else {
47. echo "Error! Query failed: <pre>{$dbLink- >error}</pre>";
48. }
49. @mysqli_close($dbLink);
50. }
51.}
52.else {
53. echo Error! No ID was passed.;
54.}
55.?>

Final Words
So, you can see file uploading process is not complex as we think. Simply think about the above-mentioned steps, and you can easily upload any kind of file in Mysql database using PHP.
