PHP

PHP, short for "PHP: Hypertext Preprocessor", is an open-source, reflective programming language used mainly for developing server-side applications and dynamic web content, and more recently, other software.

PHP allows interaction with a large number of relational database management systems, such as MySQL, Oracle, IBM DB2, Microsoft SQL Server, PostgreSQL and SQLite. PHP runs on most major operating systems, including UNIX, Linux, Windows, and Mac OS X, and can interact with many major web servers.
