stream_socket_server Create an Internet or Unix domain server socket &reftitle.description; resourcefalsestream_socket_server stringaddress interror_code&null; stringerror_message&null; intflagsSTREAM_SERVER_BIND | STREAM_SERVER_LISTEN resourcenullcontext&null; Creates a stream or datagram socket on the specified address. This function only creates a socket, to begin accepting connections use stream_socket_accept. &reftitle.parameters; address The type of socket created is determined by the transport specified using standard URL formatting: transport://target. For Internet Domain sockets (AF_INET) such as TCP and UDP, the target portion of the remote_socket parameter should consist of a hostname or IP address followed by a colon and a port number. For Unix domain sockets, the target portion should point to the socket file on the filesystem. Depending on the environment, Unix domain sockets may not be available. A list of available transports can be retrieved using stream_get_transports. See for a list of bulitin transports. error_code If the optional error_code and error_message arguments are present they will be set to indicate the actual system level error that occurred in the system-level socket(), bind(), and listen() calls. If the value returned in error_code is 0 and the function returned &false;, it is an indication that the error occurred before the bind() call. This is most likely due to a problem initializing the socket. Note that the error_code and error_message arguments will always be passed by reference. error_message See error_code description. flags A bitmask field which may be set to any combination of socket creation flags. For UDP sockets, you must use STREAM_SERVER_BIND as the flags parameter. context &reftitle.returnvalues; Returns the created stream, or &false; on error. &reftitle.changelog; &Version; &Description; 8.0.0 context is nullable now. &reftitle.examples; \n"; } else { while ($conn = stream_socket_accept($socket)) { fwrite($conn, 'The local time is ' . date('n/j/Y g:i a') .
