PHP is a widely used open source server side scripting language that is used to create dynamic and interactive web pages. PHP can be directly embedded into the HTML code and hence, is perfect for any web development. The syntax of PHP is very similar to Perl and C. PHP works on Apache web server and also supports Microsoft Internet Information Server.
Installing PHP:

If you want to use PHP for website and web applications you need three things; PHP itself, a web server and web browser. To design and develop web pages you need a web development application. In addition, if you want to create dynamic web pages, you might also need database functionalities.

I suggest you to install WampServer and Macromedia Dreamweaver. WampServer is a Windows web development environment that comes with Apache webserver, PHP and MySQL database. You can download WampServer for free using this link http://www.wampserver.com/en/download.php. For more information on how to install WampServer visit this link, http://www.wampserver.com/en/presentation.php.
Basic Syntax:

PHP block starts with and can be placed anywhere in HTML code. Each line of code ends with semicolon. Semicolon is used to separate one set of instructions from another. The example below is a simple PHP script which sends the message “Hello World” to the browser.
