note 57234 added to ref.array

Watch for strange behaviour when trying to delete by value in a integer-only array. For the following function: function my_array_delete_by_value($array, $value) { $array_flip = array_flip($array); if (isset($array[$array_flip[$value]])) unset($array[$array_flip[$value]]); return array_merge($array); } array(4) { [0]=> int(2) [1]=> int(5) [2]=> int(6) [3]=> int(8) } returns array(2) { [0]=> int(5) [1]=> int(8) } ie deletes both element 2 and value 2. ---- Manual Page -- http://www.php.net/manual/en/ref.array.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57234 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57234&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57234&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57234&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57234&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57234&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57234&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57234&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57234&report=yes Search -- http://master.php.net/manage/user-notes.php
