note 102701 added to function.usort

Probably a bug or an undocumented feature: usort() sorts your list even if you don't want to.

Detail: 
If you call usort($your_list, "your_call_back_function"), where inside the your_call_back_function() you return 0 immediately, then you would expect $your_list to be unchanged. But in fact it is changed.

Code:
<?php
function your_call_back_function($left, $right){
    return 0;
}

$your_list = array(1, 3, 2);
usort($your_list, "your_call_back_function");

print_r($your_list);
?>
