sort an array base on key

Question

i have an array like this:

Array
(
    [0] => Array
        (
            [title] => some title
            [time] => 1279231500
        )

    [1]          


        

Answer 1

You can sort it this way (since it is an associative array):

function cmp($a, $b)
{
   return strcmp($a['time'], $b['time']);
}

usort($your_array, "cmp");
print_r($your_array);
