I need get the profile-picture from facebook then user login into web app with facebook login php sdk. And then show this into
I'm using this code:
$fb = new Facebook\Facebook([
'app_id' => 'xxx...x',
'app_secret' => 'xx....xx',

$image = $user['picture'];
echo "<img src='$image' height='42' width='42'>";
exit; //redirect, or do whatever you want

Answer 1

Some error? I was checking the example of facebook docs and the access token is passing as argument with the call get()
try {
// Returns a `Facebook\FacebookResponse` object
$response = $fb->get('/me?fields=id,name', '{access-token}');
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
$user = $response->getGraphUser();
echo 'Name: ' . $user['name'];

Answer 2

You assigned at $image the array picture:
"picture": {
"data": {
"height": 50,
"is_silhouette": false,
"url": "...",
"width": 50
}
}
So to retrieve the url you should use $image['url'].
