Hi,
Just now i read carefully your previous mail....i don't know if is possible
to create a socket/used with PHP.
In principle a client socket it's some like this:
if ((sock=socket(AF_INET,SOCK_STREAM,0))<0) --create socket file
{
.perror("Can't create socket: socket()");
.exit(1);
}
servAddr.sin_family=AF_INET;
servAddr.sin_addr.s_addr=inet_addr("your_server_ip");
servAddr.sin_port=htons(atoi(port_number);
int z=send(sock,something_to_send,strlen(something),0); --return number of
bytes which was send
close(socket);
...if z is not >0 then server is not alive...
Regards,
Gelu
