If I understand correctly, the php.ini parameter zend.enable_gc (see http://www.php.net/manual/en/info.configuration.php) determines whether garbage collection is enabled:





<?php





var_dump(gc_enabled());


ini_set('zend.enable_gc', 0);


var_dump(gc_enabled());





?>





In PHP 5.3.0 this prints:





bool(true)


bool(false)





Oh, and of course gc_enable() and gc_disable() turn on or off the collection of garbage.
