I'm trying to adjust a script for a client that needs to add 5 days to a date value. Apparently date_add is a function that could be used in 5.3, but the ... guy (I'm being polite) to maintains the linux systems (if you could call it maintaining them) has 5.1.6 installed and there's almost no hope of that changing.
So I need to find an equivalent function (or need someone to write an equivalent function) for 5.1 so I can do this. I have VERY BASIC php knowledge - enough to decode and to a few simple things... this kind of function creation is out of my realm of knowledge.
Your help is greatly appreciated.
