Note Submitter: congaz at yahoo dot dk ---- Search a multi-dimensional array on keys! ------------------------------------------- I needed to search dynamically in a multi-dimen array on keys. I came up with this little neat function. It is so amazingly simple, that I actually didn't think it would work - but it does... mixed array_searchMultiOnKeys(array, array); <?php function array_searchMultiOnKeys($multiArray, $searchKeysArray) { // Iterate through searchKeys, making $multiArray smaller and smaller. foreach ($searchKeysArray as $keySearch) { $multiArray = $multiArray[$keySearch]; $result = $multiArray; } // Check $result. if (is_array($multiArray)) { // An array was found at the end of the search. Return true. $result = true; } else if ($result == '') { // There was nothing found at the end of the search. Return false. $result = false; } return $result; // End of function, } // --- Test array_searchMultiOnKeys --- $multiArray['webpages']['downloads']['music'] = 1; $multiArray['webpages']['downloads']['pressmaterial'] = 5; $multiArray['webpages']['links'] = 7; array_searchMultiOnKeys($multiArray, array('webpages', 'links')); // returns 7. array_searchMultiOnKeys($multiArray, array('webpages', 'downloads')); // returns true. array_searchMultiOnKeys($multiArray, array('webpages', 'downloads', 'software')); // returns false. ?> $multiArray / $searchKeysArray can be any size. Happy hacking...
