superblunt Posted February 23, 2009 Share Posted February 23, 2009 Hi all i found a tutorial for socket creating on the web and it it seems to work fine but to get the socket to stay open seems to be a problem for me. This is the code i got to create the socket File Name: port.php $port="1234"; $host='127.0.0.1'; set_time_limit(0); // create low level socket if(!$socket=socket_create(AF_INET,SOCK_STREAM,0)){ trigger_error('Error creating new socket',E_USER_ERROR); } // tie up socket to TCP port socket_bind($socket,$host,$port); // begin listening connections socket_listen($socket); // create communication socket $comSocket=socket_accept($socket); // read socket input $socketInput=socket_read($comSocket,1024); // convert to uppercase socket input $socketOutput=strtoupper(trim($socketInput))."n"; // write data back to socket server socket_write($comSocket,$socketOutput,strlen($socketOutput)); // close sockets socket_close($comSocket); socket_close($socket); when i execute the code the first time it seems to hang the page not sure why After i executed the port.php I run send.php witch connects to the port and sends some text info to it.Then the open.php changes it to caps and sends it back. here is the send.php: <?php // check if form was submitted if($_POST['send']){ // open client connection to TCP server if(!$fp=fsockopen('127.0.0.1',1234,$errstr,$errno,30)){ trigger_error('Error opening socket',E_USER_ERROR); } $message=$_POST['message']; // write message to socket server fputs($fp,$message); // get server response $ret=fgets($fp,1024); // close socket connection fclose($fp); echo '<h1>You entered the following message in lowercase :'.$ret.'</h1>'; exit(); } ?> <html> <head> <title>TESTING TCP SOCKET SERVER</title> </head> <body> <h1>Enter your message here</h1> <form action="newtest.php" method="post"> <input type="send" name="message" size="30" /><br /> <input type="submit" name="send" value="Send Value" /> </form> </body> </html> In the tutorial they sed to use the php cgi and add the line : php g- port.php But that did not work the g- has no meaning so i tried -f that i found somewhere. It looks like it addes it but when i try to execute the send.php Form it just does not do anything Thx for any help in advance and sorry for beaning such a noob Link to comment https://forums.phpfreaks.com/topic/146515-noob-help-socket-creating/ Share on other sites More sharing options...
