In PHP it is allowed to have a variable that is surrounded by braces in a double quoted ("") string like this:

$qry = "This is {$_GET['myname']} String";

I was wondering if it is possible to highlight the {$_GET['myname']} Differently? Currently it defaults as black.

Also what exactly is the STRING VARIABLE style? I make changes to it but I do not see any color changes in my PHP Code.
