本文实例讲述了php socket网络操作类定义与用法。分享给大家供大家参考,具体如下:
web前端测试:
<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()">关闭服务</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() 失败的原因是:".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 "连接ok\n"; } } 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(调用场所):
<?php require_once('mysocket.php'); $con = connector::getinstance(); $req = $_get['cmd']; $con->sendmsg($req); $ret = $con->getmsg(); echo $ret; ?>
应用说明:
客户端ajax发起请求调用php,然后php借助socket进一步发起请求给c++模块。
