Learn more about PHP and MySQL programming.

PHP is a widely used programming language which works on the principal of server side scripting to produce dynamic Web pages. It can be easily integrated with HTML and SQL to produce these dynamic web pages, and is often used to process the contents of a Web page form as it is more secure and reliable than JavaScript. This free online PHP programming course gives an overview of how PHP programming works in the Web environment and you will learn what certain commands and lines of code infer within a .php file and review the resultant effect on client side machines. MySQL is an open-source relational database management system which uses structured query language requests for working with data. You will learn how PHP can be combined with MySQL to create a very powerful online database engine. This free online PHP programming course will be of great interest to IT and Web development professionals who would like to learn more about using PHP and MySQL to integrate database functions into Websites, and to learners who would like to learn more about the functionality of PHP and MySQL.

Things You Should Know

Because PHP is an HTML embedded language you should have a basic understanding of HTML/XHTML and (a little) JavaScript. In the coming tutorials we will explain the PHP code, but we won’t explain the HTML code (at least not in great detail.)

What is PHP?

• PHP stands for PHP: Hypertext Preprocessor.
• As we said before it is a server-side scripting language.
• PHP is free and is an open source software product.
• The PHP scripts are executed on the server.
• PHP supports many databases (MySQL, Sybase, Oracle and many others.)
• PHP runs on different platforms (Unix, Linux, Windows.)
• PHP is compatible with almost all web-servers used today (Apache, IIS, etc.)
• A PHP file can contain plain text, HTML tags and scripts
• The PHP files can have one of the following extensions: php, php3 or phtml.

What do you need?

Before you can follow the coming PHP tutorials you need to have the following:

• Access to a web server (like Apache).
• PHP and MySQL should be installed on the web server.

The easiest way is to find a cheap web hosting plan that support PHP and MySQL (most of the web-hosting providers do.) For a couple of bucks a month you can get a virtual host. The advantage is that everything is already installed and that you can share your program (that you are going to write) with the rest of the world. If you don’t want to spend money, you can also install everything on your local machine. The easiest way is to install WAMP if you have a Windows machine and LAMP if you have a Linux machine. (WAMP = Windows Apache MySQL PHP and LAMP = Linux Apache MySQL PHP.) These packages install everything you need. Read the install manual of these packages for instructions. After installation you should have access to http://localhost in your browser.

What Can PHP Do?

• PHP can generate dynamic page content
• PHP can create, open, read, write, delete, and close files on the server
• PHP can collect form data
• PHP can send and receive cookies
• PHP can add, delete, modify data in your database
• PHP can restrict users to access some pages on your website
• PHP can encrypt data

With PHP you are not limited to output HTML. You can output images, PDF files, and even Flash movies. You can also output any text, such as XHTML and XML.

Why PHP?

• PHP runs on various platforms (Windows, Linux, Unix, Mac OS X, etc.)
• PHP is compatible with almost all servers used today (Apache, IIS, etc.)
• PHP supports a wide range of databases
• PHP is free. Download it from the official PHP resource: www.php.net
• PHP is easy to learn and runs efficiently on the server side

PHP Files

You might have noticed that our main file is now index.php instead of index.html. This is important! It tells the PHP interpreter that there's PHP code in the file to evaluate.

THE FUNDAMENTALS IN PHP

Now that we have a basic sense of why PHP exists in the first place and how we integrate PHP code into a web page, we can arrive at the happy moment where we see that all that fundamental programming stuff we learned with Processing applies to PHP (and pretty much all programming languages) too! (Also, in the example below, notice how “//” also indicates a comment in PHP.)

Variables

Differences with Processing:
• All variables in PHP must start with a dollar sign: $
• PHP does not require that you declare the data type for your variable!

Conditionals

Conditionals (if, else if, else) are exactly the same as in Processing!

Loops

Loops (for, while) are exactly the same as in Processing!

Arrays

There are several differences with how arrays work in PHP: • Again, just like with variables, you are not required to specify the the data type for an array
• You do not have to explicitly declare the size of the array in advance! This makes it especially easy to just add elements to the end of an array
• PHP allows for a special “for each” syntax to loop through an array.
• PHP allows for something called an associative array. An associative array is a list of values where each value is referenced by a “key” (String) rather than an index (integer). In other words, instead of numbering the elements of your array from 0 to 9 (10 elements total), you can name the elements of your array. Array element “fred”, array element “sue”, array element “bob”, etc. There are certain instances where this is especially convenient. Note that you can also do this in Processing, with the use of a HashMap.
• You can get the size of an array with the sizeof() function

Advanced PHP web development Framework

1.A software framework is an abstraction in which software providing generic functionality can be selectively changed by additional user-written code, thus providing application-specific software. A software framework is a universal, reusable software platform to develop applications, products and solutions which includes support programs, compilers, code libraries, tool sets, and application programming interfaces (APIs) that bring together all the different components to enable development of a project or solution. Advanced PHP web development Framework

2.Modern dynamic web development is using various web frameworks due to many of its advantages. We have listed Advanced PHP Development solutions of a number of selected frameworks such as Zend, Codeigniter and Cake PHP. All the frameworks we selected are written in PHP Scripting language and supporting all major databases, especially MySQL. All of these frameworks are following the MVC (Model View Controller) Architecture and is one of the important points which we need to consider while choosing a framework. All of these frameworks are addressing the common features needed for any kinds of web development. This includes database management, Session Management, MVC Architecture, Object Oriented Programming (OOP), Code Reusing, Caching, Security, Ajax, Web Services, SEO Friendly URLs etc. These frameworks provide libraries for handling all common actions for the Web Development. Our recommendations: Zend, Codeigniter and CakePHP

3.Zend is an Open source Web Application framework written in PHP 5. It uses the MVC Architecture and is one of the widely using frameworks. Zend is provided by Zend Technologies, The PHP Company. It has completed Five Medium to Big projects using Zend Framework. The Team Members are well experienced in providing Zend Framework development solutions. Codeigniter is an Open source framework written in MVC Architecture. This is developed by EllisLab. Codeigniter is very simple and is now considered as the starting point of studying a Web Application framework in PHP. Professionals are using Codeigniter since 2009. Our professionals can provide good quality work with minimal development time using Codeigniter. CakePHP is an Open source framework written in PHP using MVC Architecture. Our Team Members are good in providing dynamic web development using CakePHP. CakePHP uses well-known software engineering concepts and software design patterns, as Convention over configuration, Model-View-Controller, ActiveRecord, Association Data Mapping and Front Controller. Conclusion: In most of the cases, frameworks bring a helping hand to any project. But as with any tool, how much they can help very much depends on the
4.circumstances. If your site involves more content, Drupal or WordPress may be a better fit. If you’re building the next Twitter to launch ASAP, CodeIgniter or CakePHP would be good choices. If your environment is corporate, then Zend may suit better. Finally – if you feel you need to create a bespoke framework, then hire PHP developer in India. Get cracking: it’s actually quite fun!
