I have a multidimensional array below and I want to loop through it and change the value of [menu_cats] from a number to a string, which is being pulled from a database selection. Is this possible? The name of the array is 'result'. Array ( [0] => Array ( [0] => Array ( [menu_cats] => 1 [item] => Introduction [link] => needs ) [1] => Array ( [menu_cats] => 1 [item] => Needs Assessment [link] => needs/needs.php ) ) [1] => Array ( [0] => Array ( [menu_cats] => 2 [item] => Introduction [link] => knowledge ) [1] => Array ( [menu_cats] => 2 [item] => Administer Knowledge Pre-Test [link] => knowledge/pre_test.php ) ) )
