RSS Display Box

[siluet]

well, many feeds don't change too often.

the above SimplePie example for php pages:

Is there way call php script from the html page? My pages are dynamically generated html pages. I dont want changing the AddType line for PHP files to send .html and .htm files through the PHP interpreter.

For some reason, RSS Display Box not show this feed:
