Letz Learn Something 6 - The Ternary Operator

Suppose you wanted to test a condition like so:
if(bla) then
    print A
else
    print B
end if

Pretty basic stuff.  But how many lines is that? Further more, imagine if you had to do this 100 times.  I am sure your head is reeling at that thought right now.  So is there a better and efficient way?  I would say yes.  The solution would be the ternary operator.  With this operator, code like so:
<?php
    if(bla) {
?>
        print A
<?php
    } else {
?>
        print B
<?php
    }
?>

could easily be rewritten as:
<?php echo (bla ? "A" : "B"); ?>

Of course, this is an over-simplified piece of code but hopefully, you get the point.  For example, I use this all the time to determine what parts of my navigation menus to highlight on a given page, based on the URI.

Now, isn't that much easier?
