That's the ternary operator, which you'll find in a lot of languages
besides just PHP.
The above example is exactly equivalent to:
if (isset($xyz)) {
$string = $xyz;
} else {
$string = "something else";
}
In the interest of *easily readable code* I would recommend that you try
*NOT* to use the ternary much just to appear clever. Sure, it's more
compact, but it takes a couple extra seconds to figure out what's going
on VS an if/else.
