file_get_contents()怎么样？ http://php.net/manual/en/function.file-get-contents.php

$image = file_get_contents('http://cleversoft.co/wp-content/uploads/2013/08/senior-php-developer.jpg');

然后file_put_contents()吗？ http://php.net/manual/en/function.file-put-contents.php

file_put_contents('C:/Users/AlexBoey/Pictures/images/image.jpg', $image);

更新-如果您是从笔记本电脑本身运行PHP，则以上内容适用。事实并非如此。因此，除此之外，您还需要添加标题附件内容并回显内容（$ file是服务器上保存的路径，将file_put_contents更改为服务器上的某个临时位置，您可以unlink()将其回显之前）：

$quoted = sprintf('"%s"', addcslashes(basename($file), '"\\'));
$size   = filesize($file);

header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $quoted); 
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . $size);

// you can `unlink($file)` the image saved on the server
echo $image;
