note 111314 added to function.array-uintersect

Why does the user function must return three values (0, 1, -1) instead of just two? This is necesary for the correct execution of array_uintersect, as this function first ORDERS the arrays before comparing in search of the intersection. Therefore the user function is called a different amount of times one would expect. ---- Server IP: 69.147.83.199 Probable Submitter: 190.221.129.5 ---- Manual Page -- http://php.net/manual/en/function.array-uintersect.php Edit -- https://master.php.net/note/edit/111314 Del: integrated -- https://master.php.net/note/delete/111314/integrated Del: useless -- https://master.php.net/note/delete/111314/useless Del: bad code -- https://master.php.net/note/delete/111314/bad+code Del: spam -- https://master.php.net/note/delete/111314/spam Del: non-english -- https://master.php.net/note/delete/111314/non-english Del: in docs -- https://master.php.net/note/delete/111314/in+docs Del: other reasons-- https://master.php.net/note/delete/111314 Reject -- https://master.php.net/note/reject/111314 Search -- https://master.php.net/manage/user-notes.php
