用PHP的socket實現客戶端到服務端的通信實例詳解

本文詳細介紹了用PHP的socket實現客戶端到服務端的通信實例詳解，非常實用，有興趣的同學快來看看吧

一、server.php服務端：

 代碼如下 復制代碼

<?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;

//創建SOCKET

if(($sock= socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) {

    echo"socket創建失敗原因 ". socket_strerror($sock) ."\n";

}

  

if(($ret= socket_bind($sock,$address,$port)) < 0) {

    echo"創建套接字失敗原因 ". 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";

        break2;

    }

    if(!$buf= trim($buf)) {

        continue;

    }

    if($buf=='quit') {

        break;

    }

    if($buf=='shutdown') {

        socket_close($msgsock);

        break2;

    }

    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:

 代碼如下 復制代碼

<?php

error_reporting(E_ALL);

//端口111

$service_port= 111;

//本地

$address='localhost';

//創建 TCP/IP socket

$socket= socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

if($socket< 0) {

    echo"socket創建失敗原因: ". 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,處於監聽狀態..

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