==PEAR packages==
A PEAR package is distributed as a [[gzip]]ped [[tar file]]. Each archive consists of source code written in [[PHP]], {{citation needed span|text=usually in an [[object-oriented]] style|date=July 2015}}. Many PEAR packages can readily be used by developers as ordinary third party code via simple include statements in PHP. More elegantly, the PEAR [[package manager]] which comes with PHP by default may be used to install PEAR packages so that the extra functionality provided by the package appears as an integrated part of the PHP installation. Unlike the [[CPAN|Comprehensive Perl Archive Network]] (CPAN) archives, {{citation needed span|text=which PEAR took as its model|date=July 2015}}, PEAR packages do not have implicit dependencies so that a package's placement in the PEAR package tree does not relate to code dependencies.  Rather, PEAR packages must explicitly declare all dependencies on other PEAR packages.

The PEAR base [[class (computer science)|class]]es contain code for simulating [[Object-oriented programming|object-oriented]] [[destructor (computer science)|destructor]]s and consistent error-handling.  Packages exist for many basic PHP functions including [[authentication]], [[web cache|caching]], database access, [[encryption]], configuration, [[HTML]], [[web services]] and [[XML]].

PEAR means “PHP Extension and Application Repository.” It is a framework and distribution system for reusable PHP components. It extends PHP and gives a higher level of programming for all web developers. PEAR is divided into three different classes that are: PEAR Core Components, PEAR Packages, and PECL Packages. The PEAR Packages include functionality giving for authentication, networking, and file system features and tools for working with HTML and XML templates.
