Backdoor WordPress Login Script

I have created this script to allow me to quickly login to clients wordpress installs after they have royally messed things up. For example, some clients have changed their admin password and dont know which email account they have used, so this script allows me to quickly create a new user, login and reset their details without having to muck about with mysql etc.

NOTE: to use this script you do actually need to have access to the web server and upload the file to their site and then execute it through the browser.

Instructions
================================
1. create a new file called some_file_name.php
2. copy the code below into it
3. change the settings if you need to
4. execute the script via your browser at www.some_domain.com/some_file_name.php
5. delete the file after the admin user has been created <—probably a good idea.
