I think my earlier post has been misunderstood.  I am in no way advocating keeping support for PHP4 by the PHP team alive.  I voted +1 to kill support for it on the mailing list. I warned the Phorum users about it months ago.  I did the same for MySQL 4.1.

My main concern is with the tone of the GoPHP5 movement.  As I said in a comment on the previous post, I guess I never realized that a project like Drupal would be a slave to a particular PHP version.  Maybe that is what this is all about, finally freeing these projects from the bondage of legacy PHP versions. Because we don't use OOP, we have had the luxury of coding for the current PHP versions and having the code work with a large range of PHP versions.  Phorum 5.1 has been in bug fix mode for months now too.  So, we have not had to worry about PHP changes in a while.  We don't code for PHP4.  We code for PHP and whatever works works.  The minimum of 4.3.0 (now changed to fit the new definition of "requirements" that the community has adopted) on our home page means that it works, not that we code for that version.  I never considered ensuring compatibility with a 6 year old version of PHP.

If all that GoPHP5 means is  that we won't pander to the PHP4 whiners, then sure sign us up.  I will change the front page right now as a matter of fact (done).  I have no interest in testing Phorum in PHP4.  If version 5.2 works in PHP4, I guess those lazy slackers get lucky.  If not, tough.  Does that qualify for "Make an announcement on your site that by February 5, 2008 you will accept PHP 5.2 features into your codebase and will no longer provide support for lesser PHP versions?"  Heck, I will accept 5.2 features now.  I am just not sure what PHP 5.2 feature I am supposed to be that excited for.  I guess input filter is ok.  Not sure what it does really.  All the stuff I have read make it sound like a really complicated way to escape HTML in GET and POST data.  Maybe I am reading the wrong stuff.  Does someone have a good example of filter that explains why I need to use it intead of urlencode and/or htmlspecialchars?

And what does  "stop supporting all lesser PHP versions by February 5th, 2008" mean?  If someone comes to our support forums and is using PHP 5.1 do I have to refuse him support?  That seems a little rude.  How about "stop ensuring compatibility with less PHP versions".  That sounds better IMO.

Now, killing register_globals, magic_quotes, safe_mode and adding mysqlnd (I know, its going into 5.2 now) is something to get excited about.  Hmm, so maybe I should post a notice that I am accepting PHP6 code into Phorum!  Yeah, GoPHP6.org.  Darn!  The domain is taken by a squatter.  No one thought to grab it now?  It will be useful in about 2 years.  Maybe I should grab up 7 thru 10 now. =)

Death to PHP!  Long live PHP!
