PHPStubs are PHP files which describe functions, classes, and constants provided by PHP core, and third-party C extensions.

They are commonly used in IDEs for auto-completion, or static analysis tools.

This repository contains stubs for everything covered by the PHP Documentation, and also the scripts necessary to build them. The types for some functions are more precise than in the PHP Documentation. For example, instead of array often a type like string[] is used. Instead of mixed, in some cases we use something like float|string.

The code for generating stubs is released under the Apache2 license. All generated stubs automatically inherit their original license, the PHP Documentation license.

If you would like to generate stubs, you can use the provided CLI tools:

php bin/phpstubs.php generate
