Are there limitations in mysqli that make it unsuitable for use with AMP or ReactPHP?

Question

I've seen that libraries such as amphp/mysql and friends-of-reactphp/mysql implement the low-level MySQL protocol, and do not rely on any built-in extension.

Given that mysqli supports async queries, is there any reason why these async libraries cannot be based on mysqli?

Hey ReactPHP core team member here. In short you shouldn't use them (you always can but we strongly advise against it) because their I/O isn't hooked into our event loop. Meaning it can block the entire loop and everything hooked into it until it's done with what ever it does.
