Sort Array By Value Inside Another Array

[rpanning]

I'm trying to sort by using one of the values that's inside an array thats inside the first array. Here's what the array would look like.

$array[0]['ex1'] = 'foo';
$array[0]['ex2'] = 'bar';
$array[0]['ex3'] = 'fum';

$array[1]['ex1'] = 'fred';
$array[1]['ex2'] = 'jim';
$array[1]['ex3'] = 'fred';

$array[2]['ex1'] = 'pippo';
$array[2]['ex2'] = 'pluto';
$array[2]['ex3'] = 'paperino';

Now, after the array is populated (like above) I want to sort the entire $array by $array[]['ex1']. I've searched the forum for this but didn't fine anything exactly like this, similar but not exact. Any help would be great, thanks!

You can do this with array_multisort() supposedly... but I've never gotten it to work.

If I remember tommarow I'll try and post some code Iwrote to do just this. It's a select or bubblesort ( forget which, maybe both I wrote? ) so its not real fast, but it might suit your purposes.
