【socket】用PHP的socket實現用戶端到服務端的通訊____PHP

一、server.php服務端：

<?phperror_reporting(E_ALL);set_time_limit(0);ob_implicit_flush();//本地IP$address = 'localhost';//設定用111連接埠進行通訊$port = 111;//建立SOCKETif (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) {echo "socket建立失敗原因 " . socket_strerror($sock) . "\n";}if (($ret = socket_bind($sock, $address, $port)) < 0) {echo "建立通訊端失敗原因 " . socket_strerror($ret) . "\n";}//監聽if (($ret = socket_listen($sock, 5)) < 0) {echo "監聽失敗原因 " . socket_strerror($ret) . "\n";}do {//接收命令 if (($msgsock = @socket_accept($sock)) < 0) {echo "命令接收失敗原因: " . socket_strerror($msgsock) . "\n";break;}$msg = "\nPHP Test Server. \n" ."用quit,shutdown,sun...等命令測試.\n";@socket_write($msgsock, $msg, strlen($msg));do {if (false === ($buf = @socket_read($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);?>

二、client.php用戶端:

<?phperror_reporting(E_ALL);//連接埠111$service_port = 111;//本地$address = 'localhost';//建立 TCP/IP socket$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);if ($socket < 0) {echo "socket建立失敗原因: " . socket_strerror($socket) . "\n";} else {echo "OK，HE HE.\n";}$result = socket_connect($socket, $address, $service_port);if ($result < 0) {echo "SOCKET串連失敗原因: ($result) " . socket_strerror($result) . "\n";} else {echo "OK.\n";}//發送命令$in = "HEAD / HTTP/1.1\r\n";$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";?>

這兩段代碼是簡單介紹用PHP實現用戶端和服務端的通訊
client.php
server.php
具體操作,在DOS下用PHP命令開啟SERVER,處於監聽狀態..
再開啟一個DOS視窗,用PHP命令開啟CLIENT,會得到服務端的回應....
