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.
