The ?: is more of an operator. See the manual :)

I use strlen() to check if there's any data in the first key. If  
there is, use it, otherwise use the other key. As I've mentioned  
before I've come to the conclusion that it's not notably slower than  
using isset() (which would return TRUE for a var that is set, even if  
it doesn't contain any data).

For the perfectionist, note that there is no need to have the  
surrounding () in the expression. I just use it for readability. In  
actuality, I think it's technically faster to leave them out. But  
unless you know that you need to remove them, it's not an issue. Just  
mentioning it to lay off the one whould point it out otherwise :P
