使用facebook post url facebook graph api laravel php获取facebook发布数据

I am using Laravel 5.2 and Facebook Graph api v2.5.What i want to do is to get the facebook post data from the facebook post url or facebook post id from its url.

Here is what i have tried

$data = $this->fb->get('/https://web.facebook.com/fnkcrisp/photos/a.672814049531838.1073741830.608700929276484/885537761592798/',APP_ID.'|'.APP_SECRET);
$data = json_decode($data->getBody());
    echo $data->og_object->id;

but it does not give me the facebook post id so that i can use post id to get facebook post data like this

$post_data = $this->fb->get(''.$post_id.'?fields=created_time,full_picture,message,shares,likes.summary(1),comments.summary(1),permalink_url', APP_ID.'|'.APP_SECRET);

but it only give me the object id if i request data using the object id then it gives me only likes and comments

$_data = $this->fb->get($og_objectid,APP_ID.'|'.APP_SECRET);
        $_data = json_decode($_data->getBody());

kindly help me how can i fetch facebook post data using its facebook post url or how can i get facebook post id from its url.
