Can I ask you what the reason is that you didn't use the fast parameter parsing API? I am just asking this because I've just started to learn how the internals of php work, and it makes me wonder why so many functions still use the old method?

I know from the RFC that fast ZPP is for the most used functions, but my assumption is that even though the performance benefit would be negligible, having a uniform way of checking parameters could still worth the effort. What do you think?

If it makes sense to use fast ZPP in more places, then I'd love to help the PHP project by performing additional conversions.
