        $app->get('/new/getfrominsta', function () use ($app) {

        $clientId = getenv('CLIENT_ID');
        $clientSecret =$_ENV['CLIENT_SECRET'];
        $redirectUrl = $_SERVER['REDIRECT_URI'];


        $client = new Client($clientId, $clientSecret, $MyAccessToken, $redirectUrl); //use existing token to instantiate client class
        $g= $client->users()->getMedia('1234567'); //1234567 is ID of user I intend to get his post
        $self2 = json_encode($g->get());


        foreach($self2 as $instapost)
        {
            $imgURL = $instapost->images->standard_resolution->url;
            $InstaPostID = $instapost->link;

            //$checkIfInstaPostExists = $InstaModel->CheckIfInstaPostExists($InstaPostID, $imgURL); //check if post in loop already exists in db.


            print_r($instapost);
            echo "<br/>";

        }
        exit();
