This extension is a generic extension API to DLLs. This was originally written to allow access to the Win32 API from PHP, although you can also access other functions exported via other DLLs.
Currently supported types are generic PHP types (strings, booleans, floats, integers and nulls) and types you define with w32api_deftype().
Note:
This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 5.1.0.
This extension is EXPERIMENTAL. The behaviour of this extension including the names of its functions and any other documentation surrounding this extension may change without notice in a future release of PHP. This extension should be used at your own risk.
