Previous Comments: ------------------------------------------------------------------------ [2010-12-16 11:10:39] clau dot cristea at gmail dot com Description: ------------ After sorting an associative array with asort() or arsort() items having same value are reverted. Those sorting must preserve order on same value case. --- >From manual page: http://www.php.net/function.arsort --- Test script: --------------- <?php $a = array('first' => 2, 'second' => 2); $b = $a; // Save original. print "Original:\n"; print_r($a); asort($a); print "\n\nasort():\n"; print_r($a); arsort($b); print "\n\narsort():\n"; print_r($b); print "\n"; ?> Expected result: ---------------- I'm expecting that asort() and arsort() to preserve the order of items having the same value.
