PhpStorm advanced metadata

Last modified: 03 February 2022

Besides built-in “code awareness” capabilities, PhpStorm relies on external knowledge of code, which comes in the form of PHP stubs and the special advanced metadata files.

While stubs cover the Standard PHP Library components and common extensions, metadata files can be used for extending the PhpStorm functionality based on your own needs or project requirements. The basic metadata file, .phpstorm.meta.php, is bundled inside the PHP stubs package and located inside the meta folder.
