How to sort multidimensional array

[mexlinux]

Hi:
I have an array in the following form (from var_dump):

array(2) {
[0]=> array(4) {
["url"]=> string(73) "http:"
["title"]=> string(83) "Hellboy"
["content"]=> string(184) "16 Ju"
["pos"]=> int(2)
}
[1]=> array(4) {
["url"]=> string(71) "http:"
["title"]=> string(82) "HellBoy"
["content"]=> string(141) "17 Ag"
["pos"]=> int(1)
}
}

I want to sort it in the ["pos"] order.

How can I do that?

I have read about array_multisort()
but I can not make it work....

Thanks

usort($array_name, create_function('$a,$b', 'return $a["pos"] - $b["pos"];');
