PHP

Version: This content is based on PHP 5 and tested using our web hosting server farm. The focus of this content is on server-side scripting.

This content focuses on topics in common among the languages documented here so nearly all this syntax applies to most PHP development environments as well as earlier versions of PHP.

Some of PHP's syntax will look similar to Perl but with significant differences.

Note: To be clear, the subject of this information is generic PHP 5 and in some cases Delphi for PHP. Although much of the information applies to other PHP tools, we only verified the syntax and information within generic PHP and/or Delphi for PHP.
