使用Graph API将图片上传到现有的相册（或创建一个新的相册）。
将看起来像这样：

  $ args = array（'message'= &'Caption'）; 
 $ args ['image'] ='@'。真实路径（ the_image.png）; 

尝试{
 $ data = $ facebook-> api（'/'.$ album_uid。'/ photos'，'post'，$ args）; 
} 
 catch（异常$ e）{
 print< pre>; 
 print_r（$ e）; 
 print< / pre>; 
} 
 

然后通过Graph API获取上传的图片，并重定向到图片的链接，将& makeprofile = 1 添加到querystring中。用户现在将被重定向到配置文件图像裁剪页面：

  try {
 $ pictue = $ facebook-> api（'/'.$ data ['id']）; 
 header（Location：。$ pictue ['link']。& makeprofile = 1）; 
} 
 catch（异常$ e）{
 print< pre>; 
 print_r（$ e）; 
 print< / pre>; 
} 
 

Is there any way to change the user's profile picture using the graph api?

I know you can't with the rest api (reference), but I could not find anything in the new graph api.

Upload the picture to an existing album (or create a new one) using the Graph API. Will look something like this:

  $args = array('message' => 'Caption');
  $args['image'] = '@' . realpath("the_image.png");

  try {
    $data = $facebook->api('/'.$album_uid.'/photos', 'post', $args);
  }
  catch(Exception $e) {
    print "<pre>";
    print_r($e);
    print "</pre>";
  }

Then get the uploaded image via the Graph API and redirect to the image's link, add &makeprofile=1 to the querystring. The user will now be redirected to the profile image cropping page:

try {
  $pictue = $facebook->api('/'.$data['id']);
  header("Location: ".$pictue['link']."&makeprofile=1");
}
catch(Exception $e) {
  print "<pre>";
  print_r($e);
  print "</pre>";
}
