Answer 1

Use the command "chown":
chown owner filenames
To solve this problem in the future uploads, you can use the chown command:
chown($path, $user_name);
http://php.net/manual/en/function.chown.php
There is also a chmod command, if you prefer to change permissions:

Answer 2

Maybe you can change the owner within the PHP program itself (of course if you have the permission to do that) with the exec command of PHP.
For example:
exec('whoami');
See the documentation of this php instruction here: http://php.net/manual/en/function.exec.php
This could work, but only if the servers configuration allows so.
If this doesn't work, you can try also this, but again you need some priviledges to do it:
// File name and username to use
$file_name= "foo.php";
$path = "/home/sites/php.net/public_html/sandbox/" . $file_name ;
$user_name = "root";
// Set the user
chown($path, $user_name);
See the documentation of this php instruction here: http://php.net/manual/en/function.chown.php
There are some instructions in php to modify file attributes like, chmod, chown, among others.
