stream_socket_server Create an Internet or Unix domain server socket resourcestream_socket_server stringlocal_socket int&errno string&errstr intflags resourcecontext Creates a stream or datagram socket on the specified local_socket. 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. flags is a bitmask field which may be set to any combination of socket creation flags. The default value of flags is STREAM_SERVER_BIND | STREAM_SERVER_LISTEN. This function only creates a socket, to begin accepting connections use stream_socket_accept. If the call fails, it will return &false; and if the optional errno and errstr 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 errno 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 errno and errstr arguments will always be passed by reference. 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. stream_socket_server. \n"; } else { while ($conn = stream_socket_accept($socket)) { fputs ($conn, 'The local time is ' . date('n/j/Y g:i a') .
