Quoting the definition of the official website www.php.net of PHP (Hgpertext Preprocessor or Personal Home Page Tools), PHP is a server-side, cross-platform, HTML embedded scripting language. In fact, it is a language commonly used in Web programming, as well as ASP. PHP was brewing in 1994 and released its first public version in 1995. The latest version that has been released so far is PHP 4.05.
PHP is a free software that can run in most operating system environments including Windows, Linux, etc. It is often used with the free web service software Apache and the free database Mysql on the Linux platform, with the highest performance price Than, known as the "golden combination."
Perhaps the most powerful and important feature of PHP is its database support. At present, its support covers most common databases including Oracle, Sybase, MySQL, ODBC, etc. It becomes very easy to write a web page program with database functions.
When PHP developed to PHP 3.0, there was a long period of stability, so many PHP applications still use PHP3 as the extension. Most of the current systems have gradually been upgraded to PHP 4.0 and above, using PHP as the extension; and PHP and Apache combined It is common to use PHTML as the extension, so we can easily identify PHP systems on the web.
