Somebody already posted this quick solution, using PHP's built-in 
tokenizer: https://gist.github.com/colinodell/5fb5e5d474674f294a38

I don't know if there are any edge-cases it doesn't cater for, or 
undesirable side-effects, but it's certainly smarter than just a Perl 
regex. There are also examples for making code modification in the docs 
for Nikita's PHP-Parser library: https://github.com/nikic/PHP-Parser/
