Question - What is meant by PEAR in php? 
          
        
        Answer - 
        1) - PEAR is the next revolution in PHP. This repository is bringing higher level programming to PHP. PEAR is a framework and distribution system for reusable PHP components. It eases installation by bringing an automated wizard, and packing the strength and experience of PHP users into a nicely organised OOP library. PEAR also provides a command-line interface that can be used to automatically install "packages" 
2) - 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-sourced code for PHP users 
A system for code distribution and package maintenance 
A standard style for code written in PHP 
The PHP Foundation Classes (PFC), 
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 with the PEAR Group as the governing body. The project has been founded by Stig S. Bakken in 1999 and quite a lot of people have joined the project since then.
