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
• For PHP <7.3 install the symfony/polyfill-php73 as development dependency

Installation

Alternatively you may download wordpress-stubs.php directly.

Usage with PHPStan

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.

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

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.
