php4-dev 4:4.4.0-3ubuntu2 (i386 binary) in ubuntu breezy

 This package provides the files from the PHP4 source needed for compiling
 additional modules.
 .
 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.
