Fsockopen syntax

Resource fsockopen (string $ hostname [, int $ port =-1 [, int & $ errno [, string & $ errstr [, float $ timeout = ini_get ("default_socket_timeout")])

Start a socket to connect to the resources of the specified host.
Php supports goals in the Internet field and descriptions of the socket transport list supported by unix. The supported transfer list can also be retrieved using stream_get_transports ().

The socket is enabled by default in blocking mode. You can switch to non-blocking mode and use stream_set_blocking ().

If the above instance does not understand, let's take a look at it.
