Be aware that basically previous HHVM < 3.8 doesn't assist safe TLS connections, as it lacks the required stream_socket_enable_crypto() function. Returns a list of four elements: the port quantity, an opaque string representing the IPv6 tackle, the scope ID, and the flow label. If a single protocol kind exists to help this socket kind inside the tackle family, the ProtocolType could also be omitted. And socket servers, unlike many answering machines, cease sending knowledge as soon as we dangle up, so there isn't any threat that we'll get garbage the next time we join.
