# spl_autoload_register

(PHP 5 >= 5.1.0RC1)

spl_autoload_register -- Register given function as __autoload() implementation

## Description

bool spl_autoload_register ( [mixed autoload_function] )

Register a function with the spl provided __autoload stack. If the stack is not yet activated it will be activated. If no parameter is provided the default implementation spl_autoload will be registered. When registering is successful the return value is true and upon failure false is being returned.

If your code has an existing __autoload function then this function must explicity registered on the __autoload stack. This is because spl_autoload_register() will effectively replace the engine cache for the __autoload function by either spl_autoload() or spl_autoload_call().
