Pear¶

Synopsis¶

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)

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

The code in PEAR is partitioned in “packages”. Each package is a separate project with its own development team, version number, release cycle, documentation and a defined relation to other packages (including dependencies). Packages are distributed as gzipped tar files with a description file inside, and installed on your local system using the PEAR installer.
