saving picture on server - PHP Facebook - php

Question

I am trying to save the picture which you get from the $FB->get on my server. So I can get that pic and make it a profile picture when login in with facebook. The only thing now is that I don't know how to save that pic on my server. I think I need to use copy or rename function from php or something like that. As you can see I tried using it but I have no clue how I need to fix this.
$oAuth2Client = $FB->getOAuth2Client();
if (!$accessToken->isLongLived())
$accessToken = $oAuth2Client->getLongLivedAccessToken($accessToken);
$response = $FB->get("/me?fields=id, first_name, last_name, email,gender,link, birthday,picture.type(large)", $accessToken);
$userData = $response->getDecodedBody();
$fb_foto_url = $userData['picture']['data']['url'];
copy($fb_foto_url ,'assets/images/profielfotos');
$voornaam= $app->get_klant_fb($userData['first_name']);
$_SESSION['voornaam'] = $userData['first_name'];
$_SESSION['achternaam'] = $userData['last_name'];
$fb_fotoUrl = $app->saving_fb_foto($userData['picture']['data']['url']);
How I am making a user based on facebook login.
//data ophalen
$klant= $app->get_klant_fb($userData['id']);
if($klant['id'] > 0) {
//sessie klant zetten
$_SESSION['klant_id'] = $klant['id'];
} else {
//klant aanmaken
unset($query);
$query['oauth_uid'] = $userData['id'];
$query['ledenpagina_id']= $_SESSION['ledenpagina_id'];
$query['voornaam'] = $userData['first_name'];
$query['achternaam'] = $userData['last_name'];
$query['emailadres'] = $userData['email'];
$query['geboortedatum'] = $userData['birthday'];
$query['gender'] = $userData['gender'];
$query['link'] = $userData['link'];
$app->insert_query('klanten', $query);
$klant= $app->get_klant_fb($userData['id']);
if($klant['id'] > 0) {
$_SESSION['klant_id'] = $klant['id'];
}
}
This is what the develeper.facebook looks like

Answer 1

If you have the URL which it looks like..
You can do a save..
file_put_contents("your/local/server/file.png", fopen($fb_foto_url, 'r'));
However it would make more sense to me, to store the Facebook URL in your database, and simply use that.. .

Answer 2

Please try using the curl option to save the image to the server.
$fb_foto_url = $userData['picture']['data']['url'];
$ch = curl_init($fb_foto_url);
$fp = fopen('assets/images/profielfotos/photo.ext', 'wb'); //Please print out the url and replace the .ext with extension returned such as jpg/png
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
//The image will be stored by now
//Remove the copy function
But if you really don't want to edit the picture or something try getting it directly from the url so it will be automatically updated as well.
