Mike:

That's just a shorthand way to populate an array in PHP.

One of the reasons for this feature is that somewhere in your code 
you may not know what the next index should be. So, if you use --

$results[] = $next_item;

-- then the $next_item will be "automagically" added to the next 
available index in the array. So you may be right in calling it "PHP 
magic" because I have not seen this in other languages.

Understand?

Cheers,

tedd
