Sort array quickie

Hello again

It’s another one of these days where I can’t get my head around php (and the fact that I code jscript at the same time just confuses me)

I’m trying to sort an array containing arrays by using elements of the arrays - how should I do that ?


//here's what my array could look like
//I would for instance like to order my array (the top elements - fruitnames)
//by their color or the number or the type of food (fruit/veggie)

Array
(
    [apple] => Array
        (
            [0] => red
            [1] => Fruit
            [2] => 2
        )

    [salad] => Array
        (
            [0] => green
            [1] => vegetable
            [2] => 45
        )

    [carrot] => Array
        (
            [0] => orange
            [1] => vegetable
            [2] => 22
        )

)
