PHP5 is more than just OO features, SimpleXML, SPL, Filter and the newly added Date/Time functions just to mention a few. If you need any of those PHP5 is the way to go. The first version of PHP5 was released in 2004, so it's been arround for a while now. In most cases you can still use the old PHP4 style for programming with objects, but getting access to all the new features would make the update worth the effort. - Frank > On Tue, 2006-12-19 at 19:05 +0100, Niels wrote: > > Hi list, > > > > I'm writing a PHP program and I've got a number of concerns.
