note 77615 added to function.array-diff

array_diff doesn't work with arrays of objects because it compares the string-represantation of the arguments (which is always "Object" for an object). Here is an easy way to compute the difference of two arrays of objects : <?php ... function array_obj_diff ($array1, $array2) { foreach ($array1 as $key => $value) { $array1[$key] = serialize ($value); } foreach ($array2 as $key => $value) { $array2[$key] = serialize ($value); } $array_diff = array_diff ($array1, $array2); foreach ($array_diff as $key => $value) { $array_diff[$key] = unserialize ($value); } return $array_diff; } array_obj_diff ($ao1, $ao2); ?> ---- Server IP: 217.174.196.197 Probable Submitter: 82.231.24.233 ---- Manual Page -- http://www.php.net/manual/en/function.array-diff.php Edit -- https://master.php.net/note/edit/77615 Del: integrated -- https://master.php.net/note/delete/77615/integrated Del: useless -- https://master.php.net/note/delete/77615/useless Del: bad code -- https://master.php.net/note/delete/77615/bad+code Del: spam -- https://master.php.net/note/delete/77615/spam Del: non-english -- https://master.php.net/note/delete/77615/non-english Del: in docs -- https://master.php.net/note/delete/77615/in+docs Del: other reasons-- https://master.php.net/note/delete/77615 Reject -- https://master.php.net/note/reject/77615 Search -- https://master.php.net/manage/user-notes.php
