PHP is, if compiled with ZTS/TSRM, thread-safe. Some libraries used by
some extensions might not be thread safe, but basically all "usually"
used ones are thread-safe. While it is a bit complicated as some
libraries could either be compiled thread-safe or not or some might be
not thread-safe on specific systems ... but that's not PHP itself ;-)
