libapache2-mod-php5filter binary package in Ubuntu Trusty amd64

 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 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.
 .
 PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used
 open source general-purpose scripting language that is especially suited
 for web development and can be embedded into HTML.
