The purpose of PEAR is to provide.
- A structured library of open-source code for PHP users.

- To promote the standard coding style.

PECL (PHP Extension Community Library) is conceptually very similar to PEAR, and indeed PECL modules are installed with the PEAR Package Manager. PECL contains C extensions for compiling into PHP. As C programs, PECL extensions run more efficiently than PEAR packages.
PECL includes modules for
- access to additional databases
- embedding Perl or Python in PHP scripts and for
