I came across this line of code in 2

I came across this line of code in one of the sites that I maintain (I didn't originally code it) and I was curious what exactly it does.

Here's the code:
<A HREF='$PHP_SELF?order=prod_name&quot; . ($_GET[order] == &quot;prod_name&quot; ? &quot; DESC&quot; : &quot;&quot . '>

I'm not sure what the second question mark and the colon is supposed to do. Can anyone enlighten me on this??? I would greatly appreciate it!!

Thanks in advance,
Cole

Look at the second example and the text surrounding it on this page:
