Previous Comments: ------------------------------------------------------------------------ [2004-11-19 17:57:52] [EMAIL PROTECTED] This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. Yes, I was wrong, sorry. This is fixed by now. ------------------------------------------------------------------------ [2004-11-16 11:44:21] ian_mclaughlin at blueyonder dot co dot uk Thanks for your response. Variables (master_A and master_B) change even though I have performed no operation on them since assignment. All the documentation I can find does not support this behaviour. If this actually is the expected behaviour, please explain why. ------------------------------------------------------------------------ [2004-10-27 20:09:56] ian_mclaughlin at blueyonder dot co dot uk Description: ------------ this code gives the impression that array assignment is actually done by pointer sharing, when it should be done by copying. 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
