[PHP] array_search in 2-d arrays

I've a 2 D array and would like to search for vals. in the first dimension only i.e. myArray[0][0] myArray[1][0] myArray[2][0] myArray[3][0] . . . and not in the elements myArray[0][1] CODE: for($l = 0; $l < count($layer); $l++) { $key = array_search($layer[$l], $layerDes); // $layerDes
