The problem is

$url = sprintf('slipgaji/%s', base64_encode('%sfdjasgkfgdlAJGVLjlvkjlBSBHJ%s'), $file);

The prototype for sprintf is

string sprintf ( string $format [, mixed $args [, mixed $... ]] )

You only provide one place to input to with your format slipgaji/%s, so it takes the base64_encoded string and ignores $file completely. JXNmZGphc2drZmdkbEFKR1ZMamx2a2psQlNCSEolcw== is the base64_encoded string you see in your address bar. You'll want to get rid of that base64_encode() and replace it with your path to the file. It should end up something like this:

// First %s gets replaced with $new_dirname, second %s is replaced with $file
$url = sprintf('slipgaji/%s/%s', $new_dirname, $file);

In the example above, $new_dirname should be '2013/1-2013' and $file should be '2013.05.1557.pdf' to get the URL you're expecting.
