Is .htaccess enabled at all? by default apache doesn't have it
enabled in most installations.
OK, just found this in my VirtualHost file:
AllowOverride None
If you can, set this on a per directory setting in your virtualhost
setting within a <Directory> or <Location>, instead of turning on
.htaccess.
As I have to modify it anyway, maybe I'll just put it in the virtualhost
configuration file.

Yeah, it is wise to do that, enabling .htaccess is not the best of ideas.
Just for a brief reason why.. condsider a page request of:
http://yourserver/some/dir/path/file.php
apache has to check recursivly down the path to / for .htaccess before
the request can be handled; that is a lot of overhead in my opinion
and is a key point as why it is disabled by default.

Er... why? So you have to get root privs to edit your virtual conf?
there's nothing wrong with .htaccess, just a lot of people get
confused and screw things up.
.htacess is very useful.

You dont need to have root, just the proper privs to modify the
paticular virtual conf file.

There are a lot of things wrong with .htacces, but this would be more
of a topic on an apache list than here.
.htacess is very useful.
As i mentioned using .htaccess should be your last resort; there is a
big performance hit with using .htaccess and if you have the ability
dont use it and turn it off if you arn't using it.

Hi Richard,
No suggestions yet, but hopefully something will come through. Wouldn't
you know it, I had a brainstorm while writing this response. amazing
what a night's sleep will do. The key to getting a module registered is
in session.c in the function PHPAPI int
php_session_register_module(ps_module *ptr). Obvious now, isn't it :)
As for open sourcing it, that call's up to my employer, but it may
actually be a requirement (not that familiar with the license on php
source). Anyway, they're fairly pro-open souce, so it's likely that
it'll get released back into the source tree. I'd say the biggest
benefit from my point of view is not having to re-merge the changes in
for every release of PHP :)
Who do I talk to about becoming a developer on the php source?
Cheers,
Glenn.

What's up folks?
I just wanted to tell you about a thread that's going on in the spanish php
mailing list. A fellow software developer which had just started with OOP
was asking for "Hello World" examples using OOP. The examples of code he had
been doing was not that different from the usual Hello World example we all
know and love(?), so I thought he was missing the point of what was the
purpose of using OOP. This was my reply (I'll try to keep the translation as
accurate as possible):
I believe you have misunderstood what is the purpose of OOP, your objects
are not proper abstractions.
First and most important, you should define what is the problem to solve:
greet the world.
We build an abstraction of the problem and its main components: somebody who
greets and something to greet.
Here we're working with generalizations, since our main objective is to
build reusable objects. For that purpose is useful that our "saluter" could
be used to greet more than just the world.
Therefore we'll first define what kind of interaction we expect the
salutation receivers to have, in the following interface:
interface Salutable {
public function getSalutationName();
}
In this interface we have all we need to properly greet any entity: the name
we should use when doing the salutation.
Then we create the object which represents the world:
class World implements Salutable {
public function getSalutationName() {
return "World";
}
}
Now we're missing a saluter, but we're not sure which way of greeting would
be appropiate, so we prefer to create an abstract saluter and leave the
child implementation to decide the appropiate greeting:
abstract class Saluter {
abstract public function greet(Salutable $receiver);
}
In our case we need a formal saluter as we should not disrespect the world
(saying "hey! wazzup world?" could be offensive), then:
class FormalSaluter extends Saluter {
public function greet(Salutable $receiver) {
echo "Hello " . $receiver->getSalutationName() . "\n";
}
}
Finally we make our saluter greet the world:
$saluter = new FormalSaluter();
$world = new World();
$saluter->greet($world);
----
Other things you should keep in mind:
* PHP's type hinting is preety limited, in this case we would like to
indicate that the name should be provided as a string but we can't. Maybe it
would be useful to use an object as a wrapper for native strings. EDIT: I
remembered while translating this that type hinting can only be used in
function parameters, therefore this point is useless.
* En this model it seems more appropiate that the saluter is an abstract
class, since salutation works one way, but, in the event salutations became
a two way trip, an interface would be more appropiate for the saluters.
* Here we're sending the salutation to the standard output, which is
acceptable in this case, but a more complex abstration would require us to
indicate where we should procede with the salutation, and we will have to
provide an abstraction for the possible salutation enviroments.
* A factory of saluters would be a nice feature.
------------
That's it. If you find this interesting I'll try to keep up with the
translation of following posts.

Hello there,
Is there a way to check if a variable is passed by reference or if it is
just a copy. With something like is_copy or is_reference?
Thx in advance.
Is this part of the "I don't know if two vars reference the same object in
PHP4" dilemma?
Well it isn't realy my problem, but a colluage of mine.
Also it is PHP5.
But as i understand, there isn't a way to check what kind of variable it is.
Think he just needs to use a debugger then.

I guess it's dependent on your OS, but you might be able to just enable
this line in your php.ini file for the cli version:
extension=mysql.so
Your php.ini file may be found in
/etc/php4/cli/php.ini
That's where mine (PHP4) is, but it's dependent on your specific distro.
Are you on a "package type" of distro, such as Debian, Ubuntu, Fedora,
Suse or the like? Or are you compiling stuff like on Gentoo?

He's not actually *putting* it in a database, so isn't it useless to use a
mysql_ function for this...? Maybe I misunderstand Tedd and he does use a
database, as I don't see why he would need mysql_real_escape_string() for
cleaning input...

Not at present. It is being used on a closed source project for a commercial
customer which may result in a commercial application in the near future. It
works with both PHP 4 and 5, the "old" and the "new" MySQL extensions, it
aso supports PostgreSQL. It uses a data dictionary to generate all table
classes, has built-in audit logging and workflow. The main advantage is that
you can generate web applications without writing any HTML or SQL.
