关于php：直接将图片从URL复制到我的服务器，然后将其上传到WordPress的上载文件夹？

Copy image to my server direct from URL and upload it to WordPress uploads folder?

我正在尝试通过PHP脚本上传图像，如下所述。我正在从URL拍摄图像；
我已经从这篇文章中获取了参考资料实际上，就我而言，我想将其上传到WordPress上传文件夹中，其中上传了发布图片，并且您知道WordPress在运行时在'wp-content / uploads /'内创建了一个文件夹，并将其上传到那里。因此，路径($ save_path)不是在运行时决定的。

$url="http://www.google.co.in/intl/en_com/images/srpr/logo1w.png";
$contents=file_get_contents($url);
$save_path="/path/to/the/dir/and/image.jpg";
file_put_contents($save_path,$contents);

我正在尝试使用WordPress函数" media_handle_upload"上传图像，而不是" file_put_contents"，但是一旦获得文件内容($contents=file_get_contents($url);)，我就无法将文件对象传递给此函数。请协助。
