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.
