Hello, I'm trying to figure out how to subtract timestamps.

I've got a TIMESTAMP in MYSQL and would like PHP to calculate the number of days it has been up until the current date.

How do I go about doing this?

Is there an alternative to this?  The version of MySQL I am using doesn't seem to support that function.
