});
//文档网址:https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421135319

//1.将timestamp,nonce,token按字典序排序 (参数名ASCII码从小到大排序（字典序）)
    $timestamp = @$_GET[‘timestamp‘];
    $nonce = @$_GET[‘nonce‘];
    $token= "fps2";
    $signature = @$_GET[‘signature‘];

//2.将排序后的三个参数拼接后用sha1加密
    $tmpstr = implode(‘‘,$arr);
    $tmpstr = sha1($tmpstr);
//3.将加密后的字符串与signature进行对比，判断该请求是否来自微信

    if($tmpstr == $signature && isset($_GET[‘echostr‘]))

        echo $wxSdk->onclickMenu();//点击自定义菜单市出发内容
