how can I sort an array in php?

Example :

You can do sort($a).

This first Google result for "sort array php" is this:

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

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

Try this:

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