[php] Highlighting of variables in HEREDOC blocks

[blitterobject]

Hello,

I'm using Brackets and editing .php files.

I was wondering if variables in HEREDOC blocks could be highlighted in the same way as they are inside double quoted strings.

$x = "world";
print "hello {$x}"; // $x is highlighted here
print <<<HDOC
hello {$x} // $x is not highlighted here
HDOC;

It looks like the variables in double quoted strings was added here:
#2468

There is a note on that page that says "TODO: The same rules of highlighting should apply also php's HEREDOC blocks."

I'm not sure if that is being worked on but it would be a nice feature to have.

Thank you.
