re:socket_set_blocking

Hey, I have been messing with this function, and have tried various things, it seems to me that something is wrong when socket_set_blocking is set to false, fgets will fail or any number of strange results will be received, set it to true and every thing returns to normal. One thing I would like to know has anyone ever successfully used this function in conjunction with fgets before? How would you suggest to test if a fgets command has returned nothing? If socket_set_blocking is true the script just waits for a response so if none is received there is no way to time it out. here is an example of what im trying to do, of course you need something like http://www.l0pht.com/~weld/netcat/ to simulate a server app that would send something back when a request is received. $fp = fsockopen(some_ip_address_here, some_port_here, &$errno &$errstr, 30) or die ("Error connecting to remote host."); $pck = "This is a transaction request"; fputs($fp, $pck) // Send transaction request or die("Error cannot send data to remote host."); socket_set_blocking($fp, 0); while ( !feof($fp) ) { $buffer = fgets($fp, 1024) // Get transaction response or die("Error no data recieved from remote host"); } // Test to see if an response has been received, if not try a number of times before dying $status = "This is a status of an transaction request"; $i = 0; while( empty($buffer) ) { if ( $i < 2 ) { sleep(10); fputs($fp, $status) // Send status request or die("Error cannot send data to remote host."); } else { break; } if ( empty($buffer) ) { $i++; continue; } else { break; } } @fclose($fp) or die("Error cannot close remote connection"); This gives you the general functionality I am thinking of, but this wont work as when socket_set_blocking is set to true, script just hangs, set it to false it will die with the Error cannot recieve data from remote host. Please someone I need help on this one! If any one knows any or is a PHP developer in Adelaide South Australia could they please let me know?
