Does PHP have anything like Java/JSP "filters" or Zope's acquisition?

[Soefara]

What I'd like to have a request to, say, http://www.mydomain.com/Aaaa/Bbbb/Cccc

be handled by http://www.mydomain.com/Aaaa/index.php

but with the "Bbbb" and "Cccc" stored in a request variable or attribute.
This becomes very very useful when building multi-lingual websites.

This can be done in JSP/servlets using 'filters' and it is
provided in Zope through 'acquisition'.

Is there any way of making this happen with PHP ?

Thank you very much,

Soefara

I do that with Apache's ErrorDocument

0. Be sure Apache AllowOverride is set to include FileInfo
1. Create Directory "Aaaa"
2. Create an .htaccess there with
ErrorDocument 404 /Aaaa/index.php
3. Create /Aaaa/index.php as (for example):
<?php
echo $_SERVER['REQUEST_URI'];
?>
4. Go to http://www.mydomain.com/Aaaa/Bbbb/Cccc

5. and see the resulting page:
/Aaaa/Bbbb/Cccc

Wow, that's a really interesting hack, Pedro :)

I've never seen people actually use .htaccess and ErrorDocument
to filter requests like that. Thanks for sharing this - it looks
like it will do what I want :)

Hi Soefara,

We also use a .htaccess trick to get the requests to our index.php script:

RewriteEngine on
RewriteRule ^index_php/(.*) index.php?$1

(this requires your internet provider to make a setting to allow url
rewriting).

But down from index php we use request handlers, which are objects, much
like servlets, only we create a new request handler for each request (In
Java, servlets may be reused, of even handle multiple requests at the
same time). In combination with request forwarding request handlers can
act like filters: For example, this is how our website's
LicenseAgreemen tAction reacts to accepting the the license agreement
before downloading:

function doAgreed()
{
$this->useClass('Menu ', 'beheer');
$forwardData = array(
'pntType' => 'Menu',
'id' => Menu::getDownlo adMenuId(),
'download' => $this->requestData['download'],
'pntHandler' => 'WebStartDownlo adPage'
);
$this->forwardRequest ($forwardData, 'agreed');
}

This creates an instance of the class WebStartDownloa dPage and forwards
the requestData. The page then produces the output that starts the
download. As you can see it creates new requestData for forwarding
(makes the page show the download menu), only 'download' is copied from
the original requestData.
