Description of the Issue

I looked over the other Functionlist issues and didn't see this particular problem. I believe I've broken it down as much as possible:

Functionlist has an issue showing any functions inside classes when this string is present (and the functions are private, protected or public) in a php file:

$string = "\"{";

Steps to Reproduce the Issue

1. Create a test.php file
2. copy paste the following into it:

<?php
class test{
	protected function blah(){
		$string="\"{";
	}
}
?>

3. Save the file, then look at the function list. Next, take out the word "protected" or comment out the string, save, and then the function list works again.

Expected Behavior

I was expecting it to show the functions in the file even with that string in the function. I can work around it by adding a chr(123) to any string that needs an open bracket (and is followed by an escaped double quotes), but it would be nice if I didn't have to do that.

Actual Behavior

No functions were shown in the list.
