libapache2-mod-php5filter 5.2.12.dfsg.1-2ubuntu2 (amd64 binary) in ubuntu lucid

 This package provides the PHP5 Filter module for the Apache 2 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.
 .
 Unless you specifically need filter-module support, you most likely
 should instead install libapache2-mod-php5.
 .
 The following extensions are built in: bcmath bz2 calendar ctype date dba
 dom exif filter ftp gettext hash iconv json libxml mbstring mime_magic
 openssl pcre posix Reflection session shmop SimpleXML soap sockets SPL
 standard sysvmsg sysvsem sysvshm tokenizer wddx xml xmlreader xmlwriter zip
 zlib.
 .
 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. This version of PHP5 was built with the Suhosin patch.
