<?php class Foo { private $i; function __constructor($i){ $this->i = $i*$i; } } $a = array(); for ($i=0; $i<1000000; $i++) $a[($i ^ 1234567)%100] =& new Foo($i);

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
