PHP Socket Programming Process detailed

Service side (server.php)

//Set some variables$host = "127.0.0.1"; $port = 25003;//don ' t timeout!set_time_limit (0);//Create Socket$socket = S Ocket_create (af_inet, sock_stream, 0) or die ("Could not create socket\n");//bind socket to Port$result = Socket_bind ($soc  Ket, $host, $port) or Die ("Could not bind to socket\n");//start listening for connections$result = Socket_listen ($socket, 3) or Die ("Could not set up socket listener\n"),//Accept incoming connections//spawn another socket to handle Communica Tion$spawn = socket_accept ($socket) or Die ("Could not accept incoming connection\n");//Read Client Input$input = Socket_r EAD ($spawn, 1024x768) or Die ("Could not read input\n");//clean up input string$input = Trim ($input); echo "Client Message:". $input;//Reverse client input and send back$output = Strrev ($input). "\ n"; Socket_write ($spawn, $output, strlen ($output)) or Die ("Could not write output\n");//Close Socketssocket_close ($ Spawn); Socket_close ($socket); 
 
 
 
 

Client (client.php)

$host    = "127.0.0.1"; $port    = 25003; $message = "Hello server"; echo "message to Server:" $message;//Create socket$ Socket = Socket_create (af_inet, sock_stream, 0) or die ("Could not create socket\n");//connect to Server$result = Socket_c Onnect ($socket, $host, $port) or Die ("Could not connect to server\n");  Send string to Serversocket_write ($socket, $message, strlen ($message)) or Die ("Could not send data to server\n");//Get Server Response$result = Socket_read ($socket, 1024x768) or Die (' Could not read server response\n '); echo "Reply from Server
   : ". $result;//Close Socketsocket_close ($socket);

After creating the above files (server.php and client.php), do the following:

1. Copy these files from the WWW directory (assuming wamp), and place them in C:\wamp.
2. Open a Web browser and type localhost in the address bar.
3. Browse server.php First and then client.php.
