No, you do not *need* to -- it is one option, certainly, but there is no
necessity about it.
Within double-quoted strings, it is perfectly acceptable to use unquoted
array keys:
$var = "I live in the city of $_POST[cityname]";
If you prefer to quote your keys, or have more complex expressions within
the brackets, there is also the {} syntax:
$var = "I live in the city of {$_POST['cityname']}";
$field = 'city';
$var = "I live in the $field of {$_POST[$field.'name']}";
Anyway, read up on it.
