I have an email address and I want to create a unique ID based on it, so say email is me@email.com that turns into 66wyy7eu
Ive found a close solution http://www.php.net/manual/en/function.uniqid.php#96898 but it needs the input to be numeric
emails are already unique.
You can’t guarantee that a hash of the email will always be unique either.
If your using a DB. an auto-increment field will be unique
