libapache2-mod-php4 4:4.4.2-1.1 (i386 binary) in ubuntu feisty

 This package provides the PHP4 module for the Apache 2.0 webserver (as
 found in the apache2-mpm-prefork package). Please note that this package
 ONLY works with Apache's prefork MPM, as it is not compiled thread-safe.
 To use php4 with Apache 1.3, you probably want libapache-mod-php4 instead.
 .
 The following extensions are built in: bcmath bz2 calendar ctype dba dbx
 exif filepro ftp gettext iconv mbstring mime_magic openssl overload pcre
 posix session shmop sockets standard sysvmsg sysvsem sysvshm tokenizer wddx
 xml xmlrpc yp zip 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.
