Needed depth of the dimension for arrays might be different by cases, so I made this.  The default of switch might not be 'max' though.

<?php
function array_dimension($array, $option = null) {
	if(!is_array($array)) {
		return 0;
	} elseif(!$array) { // if the element does not exist
		return 1;
	} else {
		switch(strtolower($option)) {
		case 'first':
			$keys = array_keys($array);
			return array_dimension($array[$keys[0]], $option) + 1;
		case 'last':
			$keys = array_keys($array);
			return array_dimension($array[$keys[count($keys) - 1]], $option) + 1;
		case 'min':
			foreach($array as $key => $val) {
				$dems[$key] = array_dimension($val, $option);
			}
			return min($dems) + 1;
		case 'max':
		default:
			foreach($array as $key => $val) {
				$dems[$key] = array_dimension($val, $option);
			}
			return max($dems) + 1;
		}
	}
}
?>
