Re: [PHP] Are PHP5 features worth it?

Hi list,

I'm writing a PHP program and I've got a number of concerns. The program is
about 20 KLOC at the moment, but will probably grow quite a lot.

I'm using OOP throughout, and I don't really have a lot of problems with
what PHP4 can do with OOP. PHP5 does have a nice feature or two, eventhough
none seems essential to my particular style of programming. I don't mind
using what PHP5 offers where it makes sense, but where's that? Exceptions
and new OOP features?

Exceptions: I just don't see the big advantage. I've got errors and messages
bubbling up through object layers as it is, and exchanging that with a
wholly new structure seems more trouble that it's worth. I've read several
books on how cool PHP5 is, but the arguments for using exceptions seem to
boil down to "Java has them". Nowhere have I seen good examples that really
show how well exceptions solve real problems, all examples seem to show are
that 5 lines of try/catch are somehow sexier than 5 lines of if/else. What
about performance?

New OOP features: I can go through my code and mark all my methods as public
or private or whatever. No problem. But why would I? It will make classes
easier to understand when I look at them, but that's just convenience. What
are the performance benefits? I've not found a single mention of that
anywhere. What do abstractions and interfaces actually do, aside from
structuring my code better?

What major compelling reasons do I have to start using exceptions and OOP-5?

There's only one compelling reason IMHO... objects are assigned to
variables by reference instead of by copy. Other than that, as you have
noted, pretty much everything else is bells and whistles of limited use
to a savvy programmer who doesn't give a rat's ass about java style OOP.
IMHO, stick with PHP4 style coding and adjust the things that are
incompatible with PHP5. Then you're code can work in either. PHP5 uptake
has not been particularly breathtaking and the majority of PHP
developers are still using PHP4 because it works well enough without the
headaches. PHP6 on the other hand, will probably be well worth the
