}$jssdk = new JSSDK("公众号ID", "公众号密钥",$url);//按照自己的公众号填写$signPackage = $jssdk->GetSignPackage();$tmp=json_encode(array (&＃39;appId&＃39;=>$signPackage["appId"],&＃39;timestamp&＃39;=>$signPackage["timestamp"],&＃39;nonceStr&＃39;=>$signPackage["nonceStr"],&＃39;signature&＃39;=>$signPackage["signature"],&＃39;url&＃39;=>$signPackage["url"]));$callback = $_GET[&＃39;callback&＃39;];echo $callback.&＃39;(&＃39;.$tmp.&＃39;)&＃39;;exit;
?>

其它的按照动态页面参数设置即可。
