note 119657 added to function.array-udiff

Note that the compare function is used also internally, to order the arrays and choose which element compare against in the next round. If your compare function is not really comparing (ie. returns 0 if elements are equals, 1 otherwise), you will receive an unexpected result. ---- Server IP: 83.137.20.135 Probable Submitter: 93.51.246.67 ---- Manual Page -- http://php.net/manual/en/function.array-udiff.php Edit -- https://master.php.net/note/edit/119657 Del: integrated -- https://master.php.net/note/delete/119657/integrated Del: useless -- https://master.php.net/note/delete/119657/useless Del: bad code -- https://master.php.net/note/delete/119657/bad+code Del: spam -- https://master.php.net/note/delete/119657/spam Del: non-english -- https://master.php.net/note/delete/119657/non-english Del: in docs -- https://master.php.net/note/delete/119657/in+docs Del: other reasons-- https://master.php.net/note/delete/119657 Reject -- https://master.php.net/note/reject/119657 Search -- https://master.php.net/manage/user-notes.php
