本篇文章主要介紹了用PHP的socket實現(xiàn)客戶端到服務端的通信實例詳解，具有一定的參考價值，感興趣的小伙伴們可以參考一下。

一、server.php服務端：

<?php 
error_reporting(E_ALL); 
set_time_limit(0); 
ob_implicit_flush(); 
//本地IP 
$address = 'localhost'; 
//設置用111端口進行通信 
$port = 111; 
//創(chuàng)建SOCKET 
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) { 
    echo "socket創(chuàng)建失敗原因 " . socket_strerror($sock) . "\n"; 
} 
 
if (($ret = socket_bind($sock, $address, $port)) < 0) { 
    echo "創(chuàng)建套接字失敗原因 " . socket_strerror($ret) . "\n"; 
} 
//監(jiān)聽 
if (($ret = socket_listen($sock, 5)) < 0) { 
    echo "監(jiān)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客戶端:

<?php 
error_reporting(E_ALL); 
//端口111 
$service_port = 111; 
//本地 
$address = 'localhost'; 
//創(chuàng)建 TCP/IP socket 
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); 
if ($socket < 0) { 
    echo "socket創(chuàng)建失敗原因: " . socket_strerror($socket) . "\n"; 
} else { 
    echo "OK，HE HE.\n"; 
} 
$result = socket_connect($socket, $address, $service_port); 
if ($result < 0) { 
    echo "SOCKET連接失敗原因: ($result) " . socket_strerror($result) . "\n"; 
} else { 
    echo "OK.\n"; 
} 
//發(fā)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(xiàn)客戶端和服務端的通信

具體操作,在DOS下用PHP命令打開SERVER,處于監(jiān)聽狀態(tài)..

再打開一個DOS窗口,用PHP命令打開CLIENT,會得到服務端的回應....
