One, server.php service end:

<?php error_reporting (E_all);
Set_time_limit (0);
Ob_implicit_flush ();
Local IP $address = ' localhost ';
Set up 111 ports for communication $port = 111; Create a socket if (($sock = Socket_create (Af_inet, Sock_stream, sol_tcp)) < 0) {echo "Socket creation failure Reason". Socket_strerror ($sock).
"\ n"; } if ($ret = Socket_bind ($sock, $address, $port)) < 0) {echo creates socket failure reason. Socket_strerror ($ret).
"\ n"; //Listen for if ($ret = Socket_listen ($sock, 5)) < 0) {echo "Monitor failure Reason". Socket_strerror ($ret).
"\ n"; Do {//Receive command if ($msgsock = @socket_accept ($sock)) < 0) {echo command receives failure reason: ". Socket_strerror ($msgsock).
		"\ n";
	Break $msg = "\nphp Test Server. \ n "." Use Quit,shutdown,sun ...

	such as command test. \ n ";

	@socket_write ($msgsock, $msg, strlen ($msg));  do {if ($buf = @socket_read ($msgsock, 2048, Php_normal_read))) {echo "Socket_read () Failed:reason:". Socket_strerror ($ret).
				"\ n";
		Break 2;
		} if (! $buf = Trim ($buf)) {continue;
		} if ($buf = = ' quit ') {break; } if ($buf= = ' shutdown ') {socket_close ($msgsock);
		Break 2;
		if ($buf = = ' Sun ') {echo ' What are you doing? ';
		$talkback = "backinformation: ' $buf '. \ n";
		Socket_write ($msgsock, $talkback, strlen ($talkback));
	echo "$BUF \ n";

	} while (true);

Socket_close ($msgsock);

} while (true); Socket_close ($sock);?>

Second, client.php client:

error_reporting (e_all);
$service _port =;
$address = ' localhost ';
Create a TCP/IP socket
$socket = socket_create (Af_inet, Sock_stream, sol_tcp);
if ($socket < 0) {
		echo Socket creation failure Reason:. Socket_strerror ($socket). "\ n";
} else {
		echo "Ok,he he.\n";
$result = Socket_connect ($socket, $address, $service _port);
if ($result < 0) {
		echo Socket connection failure Reason: ($result). Socket_strerror ($result). "\ n";
} else {
		echo "ok.\n";
Send command
$in = "head/http/1.1\r\n";
$in. = "connection:close\r\n\r\n";
$out = ';
echo "Send Command ... ...";
$in = "sun\n";
Socket_write ($socket, $in, strlen ($in));
echo "ok.\n";
echo "Reading backinformatin:\n\n";
while ($out = Socket_read ($socket, 2048)) {
		echo $out;
echo "close socket ...";
Socket_close ($socket);
echo "Ok,he he.\n\n";

These two pieces of code is a simple introduction to use PHP to implement client and server communication
The specific operation, in DOS under the PHP command to open the server, in the listening state.
Then open a DOS window, with the PHP command to open the client, will get the service side of the response ....
