socket read and write in the same time.

[alin19]

i have this part of my code that reads from the server, if there is something output by the server and then write,

the problem is that if there is nothing to read he waits until something is there, and only after that he try to write.

 

how can i do that he tryes to read and write in the same time,?

 

 

while (true)
{

if (false === ($line = socket_read($sock,10000))) 
            echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($msgsock)) . "\n";
else	

{
        echo $line;
        }
         
        if (socket_write($sock, $order)) 
					echo "sa facut trimiterea de ordin";
					else 
					{
					echo "a aparut eroare la trimitere ordin";
					}
      }
