PHP从多维数组中提取值而没有循环

Question

I'm just wondering if it's possible to extract values from an array, in PHP, without having to loop through. Here's part of my array so you know what I mean;

Array
(
[0] => Array
    (
        [0] => 76
        [1] => Adventures of Huckleberry Finn
    )

[1] => Array
    (
        [0] => 65
        [1] => Adventures of Huckleberry Finn
    )

[2] => Array
    (
        [0] => 59
        [1] => Bookcases
    )
)

I'm after the integer [0] from each array - is there a function that can do this quicker than a foreach loop (the way I normally do this) ?

Thanks.

You eventually mean array_walk ... but this also some sort of loop? Then: the answer is no.

And I don't think that there is any quicker method (except from writing your own extension in C :-P)
