本文實例講述了PHP Socket網絡操作類定義與用法。分享給大家供大家參考，具體如下：
web前端測試：
<html>
<head>
<title>test</title>
<script>
g_xmlHttpReq = new XMLHttpRequest();
function onReplyCallback()
{
if(g_xmlHttpReq.readyState==4 && g_xmlHttpReq.status==200)
{
alert(g_xmlHttpReq.responseText);
}
}
function on_stop_service()
{
var cmd = document.getElementById("inCmd").value;
g_xmlHttpReq.open("GET","./service/main.php?cmd=" + cmd,true);
g_xmlHttpReq.onreadystatechange=onReplyCallback;
g_xmlHttpReq.send(null);
}
</script>
</head>
<body>
<input type="text" id="inCmd">
<hr>
<button onclick="on_stop_service()">關閉服務</button>
</body>
</html>
mysocket.php：
<?php
class Connector
{
public static $instance=null;
public $conn;
private function __construct()
{
set_time_limit(0);
$ip = '192.168.238.1';
$port = 8888;
if(($this->conn = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0)
{
echo "socket_create() 失敗的原因是:".socket_strerror($this->conn)."n";
}
$result = socket_connect($this->conn, $ip, $port);
if ($result < 0) {
echo "socket_connect() failed.nReason: ($result) " . socket_strerror($result) . "n";
}else {
echo "連接OKn";
}
}
public static function getInstance()
{
if(is_null(self::$instance))
{
self::$instance = new Connector;
}
return self::$instance;
}
public function sendMsg($msg)
{
socket_write($this->conn,$msg);
}
public function getMsg()
{
$clients = array($this->conn);
while(true)
{
$read = $clients;
$wrSet = NULL;
$errSet = NULL;
if(socket_select($read, $wrSet,$errSet, 3) < 1)
{
continue;
}
foreach($read as $read_sock)
{
$data = @socket_read($read_sock,1024,PHP_BINARY_READ);
socket_close($this->conn);
return $data;
}
}
}
}
?>
main.php(調用場所)：
<?php
require_once('mysocket.php');
$con = Connector::getInstance();
$req = $_GET['cmd'];
$con->sendMsg($req);
$ret = $con->getMsg();
echo $ret;
?>
應用說明：
客戶端ajax發起請求調用Php，然后php借助socket進一步發起請求給C++模塊。
