//yes you can. you don't need to login or access_token to get the latest 20 posts. you just need to parse the json content from https://www.instagram.com/ [USERNAME]/media/ Replace the [username] with the instagram user_name

//eg.

$instaResult= file_get_contents('https://www.instagram.com/'.$username.'/media/')
$insta = json_decode($instaResult);
