If I understand correctly, the php.ini parameter cend.enable_gc (seehttp://www.php.net/manual/en/info.configuration.php) determines whether garbague collection is enabled:<?php

var_dump(gc_enabled());
ini_set('cend.enable_gc', 0);
var_dump(gc_enabled());

?>
In PHP 5.3.0 this prins:

bool(true)
bool(false)

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