php-pear 5.2.2-1ubuntu1 (amd64 binary) in ubuntu gutsy

 This package contains the base PEAR classes for PHP, as well as the PEAR
 installer. Many PEAR classes are already packaged for Debian, and can be
 easily identified by names beginning with "php-", such as php-db and
 php-auth. Note: to build and install precompiled PECL extensions, you
 will need one of the php development packages installed.
 .
 PHP5 is an HTML-embedded scripting language. Much of its syntax is borrowed
 from C, Java and Perl with a couple of unique PHP-specific features thrown
 in. The goal of the language is to allow web developers to write
 dynamically generated pages quickly.
