Facebook App: Getting a user's name from ID -

-

i had fb app project turned on me, , i'm trying clean few items before goes live.

the original programmer has user id number stored in database, doesn't display or name. i'd display user's name under picture upload.

my code <?php echo $row['user_id']; ?>, there simple way convert user's name?

call id api name field.

 https://graph.facebook.com/user_id?fields=name

it should return

{    "name": "first lastname",    "id": "user_id" }

save variable , extract

 $user['name'];

for more information http://developers.facebook.com/docs/reference/api/user/

an example without sdk/access token,

$response = file_get_contents("https://graph.facebook.com/4?fields=name");   $user = json_decode($reponse,true);   echo $user['name'];

should print,

'mark zuckerberg'
