PHP's highlight_file and highlight_string functions provide syntax highlighting support for PHP. They accept a file or a string containing PHP code, and return an HTML snippet with PHP keywords, functions, and other tokens highlighted. The colors of the syntax highlighter are configured through PHP INI directives.

PHP 8.3 makes some changes to the syntax highlighter, resulting in changes to the resulting HTML output.
