如何使用PHP从用户时间线中删除推文

i want to delete tweets from user timeline from my app.For that i used:

`$retweet1=$twitteroauth->get('statuses/destroy/:id', array('id' => '570916169206509568'));

but it showing error:

    [errors] => Array
            (
                [0] => stdClass Object
                (
                [message] => Your credentials do not allow access to this resource
                [code] => 220
                )

            )

If any one having working example please post it.Thanks
