php sort array keys in multidimensional array

Question

below is my array

$myarray = Array(
[1] => Array (['mytime']=>1),
[7] => Array(['mytime']=>2),
[2] => Array(['mytime']=>3),
[3] => Array(['mytime']=>4)
);

I want to sort output of this array based on keys...

$myarray = Array(
[1] => Array (['mytime']=>1),
[2] => Array(['mytime']=>3),
[3] => Array(['mytime']=>4),
[7] => Array(['mytime']=>2)
);

I have already tried ksort($myarray) it displays 1 anyways to fix this??

ksort() does this:

ksort($myarray);

Note: sorting functions do not return a new sorted array; they simply sort the array passed, and return true or false. Thus, ksort($myarray) will return 1 when successful, and $myarray will be sorted.

It's very clear if you read the docs: http://php.net/manual/en/function.ksort.php

Yes, because ksort returns true on success and false on failure, but the array will still be sorted. Demo: http://codepad.org/tJxzCVGd – Mark Miller Oct 04 '14 at 18:15
