Browse Source 
PHP7 introduces a backwards compatable change to variable varibale syntax that requires us to use curly brackets to maintain the syntax between php5 and php7.  For more info, see https://wiki.php.net/rfc/uniform_variable_syntax#semantic_differences_in_existing_syntax for the semantic differences.
