从图谱API URL复制Facebook个人资料图片

Question

I use the following simple code to copy images from their URLs to my localhost/server; however it doesn't work when I use it with Facebook Graph API. For example:

 $url="http://graph.facebook.com/4/picture?type=large";
 copy($url,"newImageName.jpg");

Notes: No errors were shown. The image doesn't be uploaded.

How can I solve this issue?

Answer 1

I found the solution in @luschn and @Joe answers. Thanks to both of them.

$arrContextOptions=array(
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false,
),
);  
$url="http://graph.facebook.com/userID/picture?type=large";
$data=file_get_contents($url, false, stream_context_create($arrContextOptions));
$fileName = 'fb_profilepic.jpg';
$file = fopen($fileName, 'w+');
fputs($file, $data);
fclose($file);
