$functions = spl_autoload_functions();
    foreach($functions as $function) {
        spl_autoload_unregister($function);
    }

A nice way to unregister all functions.

Restore the binding to __autoload after using a spl_autoload_register() call

<?php 
spl_autoload_register(array('Doctrine', 'autoload'));

// some process

spl_autoload_unregister(array('Doctrine', 'autoload'));

// but now the old __autoload is not triggered anymore 
// you need to use :
spl_autoload_register('__autoload');

// but this will throw a LogicExeption if the __autoload 
// function is not defined yet, so use:
function autoload__ ( $className ) {
    if ( function_exists('__autoload'))
        __autoload($className);
}

spl_autoload_register('autoload__');

?>

So you can define your old __autoload in another file for example

May helps some folks in this catch 22
