What is a .php file?
PHP (.php) is a plain-text source file for the PHP language — a dynamically typed, server-side scripting language designed for web development, embeddable in HTML. Modern PHP supports classes, namespaces, type declarations, and closures, and powers a large share of web back-ends and CMS platforms.
How to use this file
Use an example .php file to test syntax highlighters, the PHP interpreter and linters (PHP_CodeSniffer, PHPStan), formatters, and parser or language-detection tooling.
