OK, so it's just the other way round - I see. Instead of deleting the entry with the highest expiry date we delete all the others: foreach ($foo as $key => $value) { $tempArray = array(); foreach ($value as $subkey => $subvalue) { // add expires value only to the temporary array for sorting $tempArray[$subkey] = $foo[$key][$subkey]['expires']; } // sort array by value descending arsort($tempArray); /* new stuff starts here */ // remove the entry with the latest expiry (the first array element) array_push($tempArray); // now unset all remaining/not needed entries foreach ($tempArray as $tempKey => $tempValue) { unset($foo[$key][$tempKey]); } } By the way, isn't there a way to filter this stuff BEFORE or WHILE the whole array is created?
