PHP模拟QQ登录，发送和接收信息的例子

PHP实例代码如下:

&＃39;;
        echo $v[&＃39;msg&＃39;] . &＃39;
&＃39;;
        echo &＃39;————————
&＃39;;
    }
}
function qqLogin($qq_num, $qq_pwd) { //登录帐号
    $data = httpGet(&＃39;http://pt.3g.qq.com/&＃39;);
    $action = preg_match("/action="( . +) ? "/", $data, $matches);
    $action = $matches[1];
    $params = array();
    $params["login_url"] = &＃39;http://pt.3g.qq.com/s?aid=nLogin&＃39;;
    $params["sidtype"] = 1;
    $params["loginTitle"] = &＃39;手机腾讯网&＃39;;
    $params["bid"] = 0;
    $params["qq"] = $qq_num;

    }
}

    $params = array();

    if (preg_match(&＃39;/消息发送成功/&＃39;, $data)) echo &＃39;发送成功
&＃39;;
