The stubs are generated from @johnpbloch's package using php-stubs/generator.

  • Sodium PHP extension as latest WordPress core uses it and compat code is removed from stubs, Sodium is included in PHP from version 7.2, in 7.1 issue pecl install libsodium or install the paragonie/sodium_compat package

composer require --dev php-stubs/wordpress-stubs

Alternatively you may download wordpress-stubs.php directly.

Usage with PHPStan

composer require --dev szepeviktor/phpstan-wordpress

The package szepeviktor/phpstan-wordpress depends on phpstan/phpstan and this one. Please do read that package's README and see the example directory over there.

Usage with Psalm

Update your Psalm config to include this section.

    <file name="vendor/php-stubs/wordpress-stubs/wordpress-stubs.php" />

Furthermore ensure WordPress core is not included in <projectFiles>.

Usage in Intellisense

If your IDE has trouble parsing all of WordPress you may find the stubs useful for enabling code completion and related features. For example there are instructions for usage with VSCode's Intelephense extension.


This package is versioned to match the WordPress version from which the stubs are generated.

Generating stubs for a different WordPress version

  1. Run modern PHP version
  2. Clone this repository and cd into it
  3. Update "johnpbloch/wordpress": "x.x.x" in composer.json with the desired version
  4. Run composer update
  5. And run ./

The wordpress-stubs.php file should now be updated.
