Manually Sorting Associative Arrays

[ShadowMage]

I have the following array:

$arrTest = array('ssmith' => array(1=>'Smith, Sally', 2=>10, 3=>50000),				 'jdoe' => array(1=>'Doe, John', 2=>15, 3=>100000),				 'jadoe' => array(1=>'Doe, Jane', 2=12, 3=>65000),				 'jbequick' => array(1=>'Bequick, Jack', 2=>18, 3=>115000));

I need to be able to sort the array based on the full name (and, obviously, maintain key associations). I cannot just use ksort because of how they are written. For example, John Doe and Jane Doe would normally have the same id (first initial followed by last name) 'jdoe'. But since the same id cannot exist, Jane's first two letters are used. This creates a problem when sorting with Jack Bequick (jbequick) because jadoe is alphabetically "higher" than jbequick. In reality, Jack Bequick should come first. I have tried to wrap my mind around how I would accomplish this, but I just can't seem to formulate a decent loop that would make this work. Any advice?

can't you just sort by fullname and add another array value with a sort number, and then sort by that number.

Not quite sure I understand what you're getting at. Could you maybe show me an example? I did find a solution using uasort, which works great, but I'd like to see your suggestion, too.
