If/Else Shorthand

Syntax: (conditional) ? if met : else;

Some examples of the normal if/else format:

if($x === 0)
{
$y = 1;
}
else
{
$y = -1;
}

//..

if(strlen($str) > 100)
{
echo $str;
}
else
{
echo "Too Short";
}

What they become using shorthand:

($x === 0) ? $y = 1 : $y = -1;

echo (strlen($str) > 100) ? $str :  "Too Short";
