You should be able follow redirects with file_get_contents by giving it a third parameter $context – in which you set the HTTP context option follow_location to 1. 通过为它提供第三个参数$context您应该能够使用file_get_contents进行重定向。在该参数中，您将HTTP上下文选项 follow_location为1。
(Although this should already be the default, and in my test getting the image data worked with file_get_contents alone already.) （尽管这应该已经是默认设置，但在我的测试中，仅使用file_get_contents即可获取图像数据。）

Her is the code that I am using and it works perfect for me. 她是我正在使用的代码，它对我来说很完美。 It also saves the picture to my server so I then have a local url (which can then be posted either back to the same user's profile or to the wall of another user/page/event/etc.) All you have to do is place it in your code where $user has a value and it should work just fine. 它还将图片保存到我的服务器，因此我有了一个本地URL（然后可以将其发布回同一用户的个人资料或其他用户/页面/事件/等的墙上。）它在您的代码中$ user有值，它应该可以正常工作。
<?
$uid = $user;
function GetTheImage($linky) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_URL, $linky);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
# ADDED LINE:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$userpicture = "http://graph.facebook.com/$uid/picture?type=large";
$sourceurl = GetTheImage($userpicture);
$save = fopen("/home/arose/public_html/mydomain.com/tmp/$uid-large.jpg", "w"); //this is name of new file that i save
fwrite($save, $sourceurl);
fclose($save);
?>

<?php
$fbid=$user_profile['id'];
$pic = file_get_contents("https://graph.facebook.com/$fbid/picture?type=large");
$filename = $fbid.".jpg";
$path="images/".$filename;
