socket_accept

Description

resource socket_accept ( resource socket )

After the socket socket has been created using socket_create(), bound to a name with socket_bind(), and told to listen for connections with socket_listen(), this function will accept incoming connections on that socket. Once a successful connection is made, a new socket resource is returned, which may be used for communication. If there are multiple connections queued on the socket, the first will be used. If there are no pending connections, socket_accept() will block until a connection becomes present. If socket has been made non-blocking using socket_set_blocking() or socket_set_nonblock(), FALSE will be returned.

The socket resource returned by socket_accept() may not be used to accept new connections. The original listening socket socket, however, remains open and may be reused.

Returns a new socket resource on success, or FALSE on error. The actual error code can be retrieved by calling socket_last_error(). This error code may be passed to socket_strerror() to get a textual explanation of the error.

This example doesn't work. You have to call socket_listen($fd) after your bind in order to accept incoming connections.

The socket returned by this resource will be non-blocking, regardless of what the listening socket is set to. This is actually true for all FCNTL modifiers.

Accepting a connection using php-sockets:





$fd = socket_create(AF_INET, SOCK_STREAM, 6 /* OR getprotobyname("TCP")*/);





$PORT = 5000;





socket_bind($fd, "0.0.0.0", $PORT);





while(true)


{


$remote_fd = socket_accept($fd);





remote_socket_client_handle($remote_fd);





}





It is simple!
