PEAR is a framework and distribution system for reusable PHP components.

PEAR is short for "PHP Extension and Application Repository" and is pronounced just like the fruit. The purpose of PEAR is to provide:

* A structured library of open-source code for PHP users

* A system for code distribution and package maintenance

* A standard style for code written in PHP, specified here

* The PHP Extension Community Library (PECL)

* A web site, mailing lists and download mirrors to support the PHP/PEAR community

PEAR is a community-driven project governed by its developers. PEAR's governing bodies are subdivided into the PEAR Group, Collectives, and a President. PEAR's constitution (adopted in March 2007) defining these groups is documented here. The PEAR project was founded in 1999 by Stig S. Bakken and quite a lot of people have joined the project.

PEAR's mission is to provide reusable components, lead innovation in PHP, provide best practices for PHP development and educate developers.
