Be wary of using stream_socket_shutdown with a TLS socket. The socket is closed without sending the "close_notify" message required by TLS protocol.

To correctly close a TLS socket, use fclose() instead, which internally calls OpenSSL's SSL_shutdown() function.

Just a note to say that if you encounter problem closing some sockets using fclose in a multi client server, you should really  give this one a try.

Spent a full day trying to resolve this issue using stream_socket_shutdown($clientStream,STREAM_SHUT_RDWR);
finally do the trick.
