PHP add key => value to each array in array

Question

Best shown in practice, I have 2-dimensional array like this:

array(3) {
    [0]=> array(2) {
        ["id"]=> string(4) "3229"
        ["name"]=> string(0) "foo"
    }
    [1]=> array(2) {
        ["id"]=> string(4) "2588"
        ["name"]=> string(4) "1800"
    }
    [2]=> array(2) {
        ["id"]=> string(4) "3234"
        ["name"]=> string(4) "8100"
    }
}

And i want to add a ["type"]=> string(0) "type1" to each array so i would get this

array(3) {
    [0]=> array(2) {
        ["id"]=> string(4) "3229"
        ["name"]=> string(0) "foo"
        ["type"]=> string(0) "type1"
    }
    [1]=> array(2) {
        ["id"]=> string(4) "2588"
        ["name"]=> string(4) "1800"
        ["type"]=> string(0) "type1"
    }
    [2]=> array(2) {
        ["id"]=> string(4) "3234"
        ["name"]=> string(4) "8100"
        ["type"]=> string(0) "type1"
    }
}

I know there is a pretty simple way how to do this with foreach and array_push() but is there some simple one-liner for this?

Answer 1

foreach ($array as &$val) $val['type'] = 'type1';

I think it's fastest way
