note 102700 added to function.usort

Probably a bug or undocumented feature: usort() sort your list even if you don't want to. Detail: If you call usort($your_list, "your_call_back_function"), where inside the your_call_back_function() you return 0 immediately, then you would expect $your_list to be unchanged. But in fact it is changed. ---- Server IP: 69.147.83.197 Probable Submitter: 80.113.160.213 ---- Manual Page -- http://www.php.net/manual/en/function.usort.php Edit -- https://master.php.net/note/edit/102700 Del: integrated -- https://master.php.net/note/delete/102700/integrated Del: useless -- https://master.php.net/note/delete/102700/useless Del: bad code -- https://master.php.net/note/delete/102700/bad+code Del: spam -- https://master.php.net/note/delete/102700/spam Del: non-english -- https://master.php.net/note/delete/102700/non-english Del: in docs -- https://master.php.net/note/delete/102700/in+docs Del: other reasons-- https://master.php.net/note/delete/102700 Reject -- https://master.php.net/note/reject/102700 Search -- https://master.php.net/manage/user-notes.php
