PHP is a widely used Open Source server-side general-purpose scripting
language that is especially suited for Web development and can be
embedded into HTML.  Its syntax draws upon C, Java, and Perl, and is
easy to learn. PHP runs on many different platforms and can be used as a
standalone executable or as a module under a variety of web servers.  It
has excellent support for databases, XML, LDAP, IMAP, Java, various
Internet protocols, and general data manipulation, and is extensible via
its powerful API. It is actively developed and supported by a talented
and energetic international team.  Numerous open source and commercial
PHP-based application packages are available.
