PHP4 scripts on PHP3

[Anon]

I wrote some scripts for php4 on my workstation but I need to upload them to a server running php3. I used functions like is_numeric() which dont seem to exist php3.

I have never written php3 scripts so I don't know what else might not work. What do you suggest I do?

You can check the manual for what version you need for a function to be present. Unfortunately I think you have to check them one by one. If you have a decent feel for the functions you should probably have some intuition over what is probably not supported.
