Note Submitter: ahigerd at stratitec dot com ---- Note that PHP uses copy-on-write so passing parameters (even array parameters) by reference gains you no performance benefit, and in fact in some cases can HURT performance. For example: php > $array = array('a','s','d','f'); php > $start = microtime(true); for($i=0; $i<1000000; $i++) byref($array); echo microtime(true)-$start; 2.40807890892 php > $start = microtime(true); for($i=0; $i<1000000; $i++) byval($array); echo microtime(true)-$start; 1.40822386742
