This is a function I built to go through a multi-dimensional array and return the difference in an array. /* * This function will go through every level of an array * to find all of the differences. */ function multidimensional_array_diff($arr1, $arr2) { //first take the differnces between the base array $diff = array_diff($arr1, $arr2); //now itterate through all of the sub-arrays, if any exist foreach($arr1 as $key => $value) { //if it found a sub-array, perform the same function if (is_array($arr1[$key])) $diff[$key] = my_array_diff($arr1[$key], $arr2[$key]); //if it returns an empty array, which sometimes it does, clear it out if (empty($diff[$key])) unset($diff[$key]); } //return the difference of the array return $diff; } ---- Server IP: 69.147.83.199 Probable Submitter: 76.21.32.198 ---- Manual Page -- http://php.net/manual/en/function.array-diff.php Edit -- https://master.php.net/note/edit/111706 Del: integrated -- https://master.php.net/note/delete/111706/integrated Del: useless -- https://master.php.net/note/delete/111706/useless Del: bad code -- https://master.php.net/note/delete/111706/bad+code Del: spam -- https://master.php.net/note/delete/111706/spam Del: non-english -- https://master.php.net/note/delete/111706/non-english Del: in docs -- https://master.php.net/note/delete/111706/in+docs Del: other reasons-- https://master.php.net/note/delete/111706 Reject -- https://master.php.net/note/reject/111706 Search -- https://master.php.net/manage/user-notes.php
