libapache2-mod-php5filter 5.3.2-1ubuntu4.1 (i386 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 Core ctype date
  dba dom ereg exif fileinfo filter ftp gettext hash iconv json libxml
  mbstring mhash openssl pcre Phar 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.
