php create folder owner/group

Question

I'd transfer my site to linux hosting, Its has an issue on uploading image to the system's auto create folder which permission is chmod 0777, I found that its always make the uploading failed because of owner/group is in www-data, how could it change owner/group to 'root' in order to upload the image into the folder?

$media_path = "../upload/".$nextid;

if(file_exists($media_path)){
//do nuthing

}else{

mkdir($media_path, 0777);
chmod($media_path, 0777);
chown($media_path, "root");
chgrp($media_path, "root");

}

Please advice. Thanks.

You cannot use chown unless you are root. But creating the folders with 0777 is sufficient to allow anyone to write to them.
