Title: Added test for variable variables in PHP

Test fails. Only the second dollar sign gets wrapped in a span.

I thought fixing this would be as simple as adding a plus after the `\$` in the php.js file (line 17), however, that doesn't work. I strips out a dollar sign:

`'pattern': /(\$+)(\w+)\b/g`
