PHP sort multidimensional array by date

Question

I\'m having a problem. I have a multidimensional array, that looks like this:

Array ( [0] => 
              Array ( 
                    [0] => Testguy         


        

Answer 1

function cmp($a, $b){

    $a = strtotime($a[2]);
    $b = strtotime($b[2]);

    if ($a == $b) {
        return 0;
    }
    return ($a < $b) ? -1 : 1;
}

usort($array, "cmp");

Or for >= PHP 7

usort($array, function($a, $b){
    return strtotime($a[2]) <=> strtotime($b[2]);
});
