Question

I have multidimensional array with many values, this is minimized version of it:

$test = array(
    array(
       'name'   => 'test',
       'date'   => '2012-04-30 11:06:01'
    ),

    array(
       'name'   => 'test2',
       'date'   => '2012-04-30 11:07:00'
    )
);

And it just goes on…

Now dates are in random order, so i need to sort this array so it would be from smallest date to the biggest one, to be more clear i here is my full scale array dump: http://pastebin.com/EzTNJpUx and as you can see sent is the date and it goes in random order…

Answer 1

Use usort

From Manual:

This function will sort an array by its values using a user-supplied comparison function. If the array you wish to sort needs to be sorted by some non-trivial criteria, you should use this function.

function cmp($a, $b){
     return strtotime($a['date'])-strtotime($b['date']);
}

usort($test, 'cmp');
