I needed a way to flip a multidimensional array and came up with this function to accomplish the task. I hope it helps someone else. function multi_array_flip($arrayIn, $DesiredKey, $DesiredKey2=false, $OrigKeyName=false) { $ArrayOut=array(); foreach ($arrayIn as $Key=>$Value) { // If there is an original key that need to be preserved as data in the new array then do that if requested ($OrigKeyName=true) if ($OrigKeyName) $Value[$OrigKeyName]=$Key; // Require a string value in the data part of the array that is keyed to $DesiredKey if (!is_string($Value[$DesiredKey])) return false; // If $DesiredKey2 was specified then assume a multidimensional array is desired and build it if (is_string($DesiredKey2)) { // Require a string value in the data part of the array that is keyed to $DesiredKey2 if (!is_string($Value[$DesiredKey2])) return false; // Build NEW multidimensional array $ArrayOut[$Value[$DesiredKey]][$Value[$DesiredKey2]]=$Value; } // Build NEW single dimention array else $ArrayOut[$Value[$DesiredKey]][]=$Value; } return $ArrayOut; }//end multi_array_flip ---- Server IP: 69.147.83.197 Probable Submitter: 75.244.105.167 ---- Manual Page -- http://www.php.net/manual/en/function.array-flip.php Edit -- https://master.php.net/note/edit/107097 Del: integrated -- https://master.php.net/note/delete/107097/integrated Del: useless -- https://master.php.net/note/delete/107097/useless Del: bad code -- https://master.php.net/note/delete/107097/bad+code Del: spam -- https://master.php.net/note/delete/107097/spam Del: non-english -- https://master.php.net/note/delete/107097/non-english Del: in docs -- https://master.php.net/note/delete/107097/in+docs Del: other reasons-- https://master.php.net/note/delete/107097 Reject -- https://master.php.net/note/reject/107097 Search -- https://master.php.net/manage/user-notes.php
