Reproduce code: --------------- <?php // $master_A=array(1,2,4,3); $master_B=array(1,3,2,4); $A = $master_A; $B = $master_B; echo"<br/>BEFORE MULTISORT"; echo"<br/>master_A<br/>"; print_r($master_A); echo"<br/>master_B<br/>"; print_r($master_B); array_multisort($A, $B); echo"<br/>AFTER MULTISORT"; echo"<br/>master_A<br/>"; print_r($master_A); echo"<br/>master_B<br/>"; print_r($master_B); ?> Expected result: ---------------- BEFORE MULTISORT master_A Array ( [0] => 1 [1] => 2 [2] => 4 [3] => 3 ) master_B Array ( [0] => 1 [1] => 3 [2] => 2 [3] => 4 ) AFTER MULTISORT master_A Array ( [0] => 1 [1] => 2 [2] => 4 [3] => 3 ) master_B Array ( [0] => 1 [1] => 3 [2] => 2 [3] => 4 ) Actual result: -------------- BEFORE MULTISORT master_A Array ( [0] => 1 [1] => 2 [2] => 4 [3] => 3 ) master_B Array ( [0] => 1 [1] => 3 [2] => 2 [3] => 4 ) AFTER MULTISORT master_A Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 ) master_B Array ( [0] => 1 [1] => 3 [2] => 4 [3] => 2 ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30587&edit=1
