php4 supergloabals

[rlhanson]

I have inherited a website that is what another programmer describes as the perfect example of overuse of procedural programming...

The site is a custom shopping cart solution with many pages being created by php if statements based on anchor id's and htaccess rewrites.

Most of the code uses superglobals for the programming.

If you inherited this site, what would you be concerned about?

What security issues would be relevant?
What recommendations would you make to the client for php5 compatibility?

Please share your thoughts on this - I need to make an informed decision and recommendation to my client.
