PHP is a server-side, Cross-platform, HTML-embedded scripting language, as defined by the official site www.php.net referencing PHP (hgpertext preprocessor or personal home Page Tools). In fact, it is as familiar as the ASP, is a commonly used in the Web programming language. PHP was conceived in 1994, and its first public version was released in 1995, up to the current release of the latest version of PHP4.05.
PHP is a freeware software that runs in most operating systems, including Windows, Linux, and so on, and is often used in conjunction with free web services Apache and free database MySQL on Linux platforms with the highest performance-price ratio, known as the "Gold portfolio."
Perhaps the most powerful and important feature of PHP is its database support, which currently covers most common databases, including Oracle, Sybase, MySQL, ODBC, and so on. It's easy to use it to write a Web program that contains database functionality.
PHP developed to PHP 3.0 when there is a fairly long period of stability, so many PHP applications are still PHP3 as extensions, now most of the system has been gradually upgraded to PHP more than 4.0, using PHP as an extension; while PHP is used in combination with Apache, Phtml is usually used as an extension, so we can easily identify the PHP system on the network.

PHP is a language that was born on the web, used for networking, and developed on the web. It was born to be branded as a free development. At home and abroad, there are thousands of individuals and organizations in various forms, languages to learn, develop and improve it, and constantly publish the latest applications and research results.
