Thank you @aqib, this partially solves my problem but I would also like to provide an auto login link to PHPmyadmin. The password, I have noticed, is encrypted in exactly the same way so I still need to work out how to encrypt the plain text password in PHP before sending the encrypted version in the URL parameter to log the user in. Unfortunately, installing PHPmyadmin yourself doesn't work, as you can only access the databases through iFastNet's specially setup version.
