I just spent a good portion of this afternoon updating GroupOrg to PHP5 strict so that we can fully 'take advantage' of PHP5. It was nice to be able to declare vars and functions private with adding only a single line of code.
However, as I went through our code, I realized that we have a long ways to go before we are truly taking advantage of PHP5. I noticed in several areas where we added hacks because of the way PHP4 functioned. Hopefully, we will be able to work beyond that and we can produce a program that is a model for PHP5 programming, but only time will tell...
