 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

 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.
