The {} only become really useful when you're trying to reference arrays
within a string:
$var = array('great', 'boring');
$text = "this is {$var[0]}.";
Without the curly braces, PHP wouldn't be able to figure out whether you
wanted the end string to be 'This is great.' or 'This is [0].' despite
the variable itself clearly being an array.
