Question

I’ve taken a look at a few googles and actually found this stack too: How to sort a date array in PHP

I’ts on the same wave length but i’m not sure i get it clearly. I’ve read over the phpnet documentation too… As I said, i’m feeling shakey from it.

I have an array:

Array
(
    [0] => Array
        (
            [created] => 2012-06-06 21:26:25
        )

    [1] => Array
        (
            [created] => 2012-06-06 21:23:45
        )

)

And I basically need to sort this array so that they are in date order.
How does this call back function work for usort? Any examples would be great!

Answer 1

function MySort($a, $b)
{
    if ($a['created'] == $b['created']) return 0;
    return $a['created'] < $b['created'] ? -1 : 1;
}

then use…

usort($myarray, "MySort");
