libapache2-mod-php4 4:4.3.8-3ubuntu7.14 (i386 binary) in ubuntu warty

A server-side, HTML-embedded scripting language
 This package provides the loadable module for the Apache2 webserver. Compiled
 in modules are: bcmath, calendar, curl, dba, exif, filepro, ftp, mm, sockets,
 wddx, xml, yp and zlib.
 .
 PHP4 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.
 .
 The most significant change between php3 and php4 is the new parser engine
 called Zend, which boosts performance quite impressively.
