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.
Ehh what? This has never been a problem for me:
$text = "this is $var[0].";
However this does give an error (or notice, don't recall, haven't seen
the error in quite a while):
$text = "this is $var['0'].";
In that case the solution is the curly brackets:
$text = "this is {$var['0']}.";
