Re: How to generate a hash that is valid for 48 hrs?

I wouldn't bother trying to include (and parse out) the date in the
hash. Create a table to store the hashes and include a "created
DATETIME DEFAULT NULL" column. This way, you can later use your DB's
date/time functions to check if it's within the 48 hours. When the
hash is used, remove it from the DB.
