PHP中的socket實現用戶端到服務端的通訊執行個體詳解

本篇文章主要介紹了用PHP的socket實現用戶端到服務端的通訊執行個體詳解，具有一定的參考價值，感興趣的小夥伴們可以參考一下。

一、server.php服務端：

<?php error_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 $port = 111; //建立SOCKET if (($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:

<?php error_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

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....
