creating XML with embedded PHP

[Troy]

Hi-

I am attempting to set up an RSS feed using PHP. It would be convenient for
me to embed PHP into an xml file like I would do to an HTML file in order to
create the XML, however the apache server does not realize that it's PHP
content and the PHP engine is not run against that code. so I have to call
it feed.php instead of feed.xml, and most of the rss readers don't
appreciate this.

My alternative is to create the XML file every day or so (using PHP or
whatever), however that does not guarantee that the person requesting the
rss feed gets up to date info.

I would really like to know if there is a way to create the XML file on the
fly using PHP without modifying the apache server.

Thanks,
troy

They _shouldn't_ care so long as you send the appropriate Content-type header
(Content-type: application/xml , I think).

Depends whether you count this as "modifying" the server, but a ForceType
directive in a .htaccess file might do the trick:

http://httpd.apache.org/docs-2.0/mod/core.html#forcetype

<Files "feed.xml">
ForceType application/x-httpd-php
</files>

Re: creating XML with embedded PHP

Try putting a dummy .xml filename into the url.

http://www.somewhere.krakow.pl/feed.php/feed.xml

When Apache fails to find the file /.../feed.php/feed.xml, it'll run
/.../feed.php instead.

Setting the content-type header should work though. And depending on how
popular the feed is, generating a static version of the file isn't a bad
idea. You would update the file whenever you add a new story. Since that
should happen less often then retrieval of the feed, it's more efficient.

Is it an idea to keep the script named feed.php, but make the url point to
feed.php?ext=.x ml
The script would of course do nothing with the extra variable that is
created with this method, but it might satisfy the RSS readers. I really
wouldn't know, cuz I know nothing about RSS at all, but it was just an idea
not including server modifications.

You may want to try these classes to generate a XML RSS feed:

Re: creating XML with embedded PHP

Chung suggested this and I agree that it makes a lot of sence to update the
XML file only after submission of new stuff.

This works, except in order to create the file in public_html/rss I need to
alter the permissions on feed.xml to 666 since my the webserver user had no
permission to write in my personal user directory. I don't want to leave it
with 666 perms, so is there another way to do this, or should I let the
webserver user own that file?

Thanks!

Re: creating XML with embedded PHP

The answer is nope, unless your're the server administrator.
