        if(isset($sess)){

            $request = new FacebookRequest($sess, 'GET','/me');

            $response = $request->execute();
            $graph = $response->getGraphObject(GraphUser::classname());

            $name = $graph->getName();
            echo "hi $name";

        }else{

            echo '<a href="'.$helper->getLoginUrl().'">Login with facebook</a>'

        }

?>

Answer 1

你错过了一个;在echo语句的末尾。因此错误。

所以在最后的else语句中重写为：

}else{

    echo '<a href="'.$helper->getLoginUrl().'">Login with facebook</a>';
 }
?>

PHP - 用Facebook登录
