PHP Manual¶
The PHP Manual is the official documentation for the PHP language. It covers the language syntax, all built-in functions, extensions, and ChangeLog entries for each PHP version.
The manual is collaboratively maintained and translated into many languages. Each function page includes a description, a signature with parameter and return types, a changelog, usage notes, and user-contributed comments that often provide practical examples and gotchas.
The manual is available offline through the downloadable many HTML files or single-page HTML formats, and is integrated into most PHP IDEs as hover documentation. The URL scheme php.net/function-name provides a shortcut to any function page.
<?php
