Thanks for article...
Some of it is a bit over my head, but I get the general gist!
One thing that has me confused is the usort example.
Should this line:
return ( $personA["age"] < $personB["age"] ) ? -1 : 1;
Have "name" for $personA ?
Cheers, Dave

name??

That line is the equvalent of



<?php>
if($A < $B) {
      return -1;
} else {
      return 1;
}
?>
