Sorting Array

[alsaffar]

Hi there,

I have a multi-dimensional array as follow:

$x[1][1]='C';
$x[1][2]='A';
$x[1][3]='B';
$x[2][1]='F';
$x[2][2]='X';
$x[2][3]='D';

How can I sort the array first on $x[][2] then on $x[][3]?

Please guys, any help!

have you looked at the sort() function ?

 

[alsaffar]

yes, it sort only the first index!

I don't know that I follow exactly...

Are you sorting only on values? Then you can just use array_multisort... are you trying to sort by a mix of keys and values? That's maybe a little trickier... but usort should still be useable for it.

Otherwise, you could just write your own sorting function... the built in ones aren't always the right route.

Perhaps you could clarify the question a bit for me though... you have it listed above as you'd like the sort to come out in the end?

I think that would just be something akin to

$x = ksort($x);

foreach ($x as $key=>$second_level)
{
  $x[$key] = ksort($second_level);
}

No?
