As always when it comes to PHP and FFI I'd like to point out ext-psi [1]
which uses a different approach than other PHP FFIs until now.

It parses PSI files at startup, which basically are C header files
augmented with the PHP userland interface decls, see for example the PSI
file for time.h [2]

As you can see, marshalling from and to native types has been taken
seriously, and while we're capable of recursively unmarshalling e.g.
addrinfo structs [3] and handling sqlite callbacks [4] it's still not
possible yet for something like curl_easy_setopt.
