normalize_uri() should be used when you're joining URIs. Because if you're merging URIs after it's normalized, you could get double slashes again.

This module exploits a vulnerability in the lib/functions.php that allows
|
|
attackers input parsed directly to the create_function() php function. A patch was
|
|
issued that uses a whitelist regex expression to check the user supplied input
|
|
before being parsed to the create_function() call.
