[geeklog-devel] Re: GL2: php5?

[Chris Franklin]

I agree - it's pretty optimistic to think that php5 will be ready to go any time soon. However, I think it would be wise to understand the language features/syntax and design/write GL2 such that it can be easily ported to php5/zend2 when the time is right. 
Of particular interest are namespaces/imports, constructors/destructors, and exception handling. A quick look at Tony's code shows he already is thinking namespaces which is great. 

Tony - I have regular access to the irc channel... I'll try to monitor it going forward... if I'm not on, just send me an email.

My $0.02

I've been keeping up with PHP5 and with everything going on I'd honestly
be surprised to see a stable version this year. And I really don't know
about a beta this month. My gut is telling me to not expect to see a
"real" beta until summer. But then again, you never know. I wouldn't
focus on PHP5 too much, even if it is released, adoption will be slow.

PHP5 isn't going to be a huge change like everyone thinks it is. It's
going to be huge internally, but its going to be BC so not to worry to
much.

Chris,

I'm not ignoring you, I thought I got back to you through a post on 
geeklog-devel. Anyway, this is where most of these sorts of discussions

should occur (I have copied this list in).

I have a number of tasks you could be working related to GL2 that I
think 
warrant value despite any release of PHP5 engine. So here are a few 
response to your message below:

1) Embarassingly enough, I have not followed PHP5 other than the
wishlist 
they began work from. Your mentioning this is a good reality check. I 
haven't read the article yet but I'll be interested in any projections
in 
final releases and I have questions related to backwards compatibility.

2) Because GL2 has started out OO, I'm hoping much of our existing GL2 
code (what little exists) will port nicely so I think we got with what
is 
stable but plan for any changes we may need to make. This will require
us 
to do a bit of research

3) As I said, I have a number of tasks to help ramp you up on GL2. Are 
you able to connect to our IRC channel on a regular basis or will a bulk

of our conversation have to take place on this list? Regardless, I will

touch base with you soon on what we have so that you might get started 
ASAP.
