[UPHPU] short syntax without the else?

Nope. It's called the ternary operator, because there are 3 parts to it. 
The ':' and the operand after it are required.

You can, however, use the short-circuited && operator like this:

    $condition && $var = "this";

Here's an example:

   $condition = false;
   $var = "bar";

   // Here's the magic
   $condition && $var = "foo";

   echo $var;

If $condition is true, this will output "foo", otherwise, it'll output 
"false".

This is called short-circuited because the interpreter is smart enough 
to not evaluate the second half of an && if the first half is false.

Be sure to use parentheses when your condition has multiple conditions, 
like this:

   ($condition && $other_condition) && $var = "foo";

Enjoy!
