I'm kind of coming from the outside here, so forgive my ignorance on some matters. I have some OO experience, just not with PHP and have only worked with PHP4 so again.. kind of on the outside of all this. Rasmus, you make a great point here. OO is structured and is all about constraints whereas PHP tends to be rather flexible. So OO in PHP doesn't mean that it should comprompise the idea of a structured development method. It's just part of PHP's philosophy of allowing developers to choose their method of skinning the proverbial cat. It seems that one of Jochem's main complaints about it isn't so much the rules and structure, but the idea that he was told his code was wrong and he needed to redo a good chunk of his 2 years worth of development (or any of this code) to PHP5's OO standard then a short time later he's told that someone else had the same problem and the 'standard' was changed to accomodate. But hey.. stuff happens. Sometimes concessions need to eventually be made when there's no other way. So that leads me to the 'sell' part of my altered subject line. Rasmus said: "People are not upgrading to PHP 5 because PHP 4 works just fine for them and they haven't yet discovered things like SimpleXML and some of the other killer features of PHP 5." So I've read some of the new features on PHP5 and am still not sold on upgrading. As was stated, what we've developed so far works great and there's no real incentive to upgrade. But upgrades are inevitable so in the interest of planning for the future, I'm looking at PHP5. Our XML routines work fine, but since you mentioned SimpleXML, I'll take a closer look at it. What are some of the other "killer features" of PHP5 that I may be sleeping on here. "If it ain't broke, don't fix it" works for a while, but if there are easier and/or better ways to do things in PHP5, I want in! So someone sell me on this from the point of view of someone who's upgraded and has learned the joys of PHP5. So far what I've found online has been little more than a list of new features without an idea of how much of a headache they're going to save me in the future.

And on the OO side your argument gets shaky as well. The whole point of OO is to add a very structured layer on top of your code to make it more consistent and more maintainable than the equivalent procedural code. There is nothing you can do in OO that you can't do with completely freeform procedural code. When you choose to go OO, you choose a set of rules and a certain code structure that by definition is going to be somewhat constrained. The argument over exactly how constrained this should be and where we should loosen things up will continue until the end of time. PPP and Interfaces are all about constraints. They serve no practical purpose whatsoever other than to add constraints. And saying that these OO issues is slowing down PHP 5 uptake is a bit of a red herring. We are competing against ourselves. PHP 4 works extremely well. There is a lot of code written for it and it works. I seriously doubt very many people are not upgrading to PHP 5 because of some debatable edge-case OO thing. People are not upgrading to PHP 5 because PHP 4 works just fine for them and they haven't yet discovered things like SimpleXML and some of the other killer features of PHP 5. -Rasmus ___________________________________________________________ Sent by ePrompter, the premier email notification software.
