Unwrap variable only from complex string about php-cs-fixer HOT 2 CLOSED

I think this should use the (string) cast to keep the same behavior:

-$a = "{$msg}";
+$a = (string) $msg;
-$a = "{$obj->msg}";
+$a = (string) $obj->msg;
$a = "{$msg} "; // do nothing, complex string consists of more than a variable

Why would this be limited to complex strings though? Couldn't the fixer also fix

-$a = "$msg";
+$a = (string) $msg;

?

should this be part of single_quote fixer?

I don't think so, this looks like an entirely new feature to me and I would create a new fixer.

Good point with the cast. I did not realized it when I was opening this issue. I probably do not want to pursue this issue then and simply find and fix issues in our codebase using "\{\$.+\}" regex.
