note 74912 added to function.array-multisort

I didn't see this noted anywhere, so I figured I'd put in a little comment regarding arrays located inside classes. For instance: class abc { var $data; } The following code does not act as expected: $clsVar =& new abc(); foreach ($clsVar->data as $key => $row) { $position[$key] = $key; } array_multisort($position, SORT_DESC, $clsVar->data); While I realize this could much easily be acheived using ksort(), this is merely a much more simple example of this behaviour. The exerpt above comes from a much more complicated sort using multi-scripted arrays. Anyway the only way I could find to get around the behaviour of multisort not sorting the referenced class-array was to make a copy of it as below: $clsVar =& new abc(); $newData = $clsVar->data; foreach ($newData as $key => $row) { $position[$key] = $key; } array_multisort($position, SORT_DESC, $newData); Now newData will contain the sorted array as expected. Hopefully this helps someone else! ---- Server IP: 64.71.164.2 Probable Submitter: 12.38.98.215 ---- Manual Page -- http://www.php.net/manual/en/function.array-multisort.php Edit -- https://master.php.net/note/edit/74912 Del: integrated -- https://master.php.net/note/delete/74912/integrated Del: useless -- https://master.php.net/note/delete/74912/useless Del: bad code -- https://master.php.net/note/delete/74912/bad+code Del: spam -- https://master.php.net/note/delete/74912/spam Del: non-english -- https://master.php.net/note/delete/74912/non-english Del: in docs -- https://master.php.net/note/delete/74912/in+docs Del: other reasons-- https://master.php.net/note/delete/74912 Reject -- https://master.php.net/note/reject/74912 Search -- https://master.php.net/manage/user-notes.php
