Answer 2

You can use array_multisort , specially if your inner arrays has same size. I have checcked it, hope it will serve as you need.

Answer 3

1. Why your array is multidimensional?
2. Join your nested arrays into one, sort it, and then you can output that sorted array in a manner you wish

Answer 4

Try this:

$resort = "return (1*strnatcmp(\$x['0'], \$y['0']));";
uasort($a, create_function('$x,$y', $resort));
print_r($a);
