PHP4
PHP4 is a popular, freely available web applications development
tool. PHP4 includes an HTML-embedded scripting language and a server-side preprocessor that
interprets the HTML-embedded code in order to create dynamically generated web pages. PHP4 also
supports several databases, including mSQL,
MySQL, and PostgreSQL,
and is commonly used for the development of database enabled web sites.
PHP4 is the newest version of PHP. It became available on May 22, 2000 and offers improved
performance, scalability, features, and extensibility over previous versions.

PHP4.1.2 or earlier, we strongly encourage you to upgrade to version 4.2.2. |
