fsockopen trouble

I'm quite new to sockets, I'm using fsockopen to communicate with a server. What i want to do is communicate with a server get a response back then communicate again and get another response back. The first exchange goes fine but the second doesnt seem to work?

Code:

//$fp is a valid socket, using fsockopen
fwrite($fp, $socks_header);			
print fread($fp, 2048);
fwrite ($fp, $header);
print fread($fp, 2048);

PHP:

Thanks

 

try to close the connection first after reading and then communicate again

Regards

The problem is that i need both communications to be in the same connection.
I think the problem may be that it doesnt think that the first communication has finished?
