Array Sorting in php?

Question

I have multiple arrays in in this format:

array = array(
    [0] => String
    [1] => String
    [2] => 1234
)

All of these arrays are contained in a single array. Is there any way i could sort each array in the Main array by the Number [2] from Highest to lowest. I have seen things like rsort(), but never got them to work. Thanks.

I just tried this, but it does not work for the last array?

function sortByOrder($a, $b) {
    return $a[1] - $b[1];
}

$array = array(array("sdfdf", "dddfg", 153), array("dd", "dd", 80), array("dd", "ddd", 155));

usort($array, 'sortByOrder');
print_r($array);

U need a[2] as highest and a[0] as lowest. Looks like u have issues with http://www.php.net/manual/en/function.rsort.php. Can u explain what is the problem ? — Tectrendz, Dec 26 '13 at 22:06

@Tectrendz What do you mean? I just need the array with the highest Int to go to the top — Hunter Mitchell, Dec 26 '13 at 22:09
@bleuscyther This looks like what i need. Could you post an answer with some code. Also, he is using Keys with text, and i am using numbers. How would i do it my way? — Hunter Mitchell, Dec 26 '13 at 22:11

After further research i figured out that i could use this:

$array = array(array("sdfdf", "dddfg", 153), array("dd", "dd", 80), array("dd", "ddd", 155));

usort($array, function($a, $b) {
    return $a[2] - $b[2];
});

print_r(array_reverse($array));

Then reverse the order of that array.
