Q:

How do I check if a RSS feed is working?

For example, if there is an RSS feed and for some reason it is down or cannot be grabbed I want to display a simple message saying "feed cannot be grabbed".

Right now PHP spits out a really ugly warning message.

note:I do not need to know whether it is valid. I just need to know if the feed actually works. I do not want to turn off warnings. I want to spit out a simple echo if the feed is not working. I am using PHP no libraries.

Any thanks would be awesome!

A:

You can manually handle any XML parsing errors by using the libxml_use_internal_errors function.

An example can be found here

That was helpful, but I am still getting this error. (The url is an incorrect one, so I could test)Warning: DOMDocument::load(http://rss.cnn.com/rss) [domdocument.load]: failed to open stream: HTTP request failed! HTTP/1.0 404 Feed not found error: FeedBurner cannot locate this feed URI. in /home/content/r/i/c/rickchendesign/html/twg/rssLib.php on line 17

Indeed it seems that there is no way to suppress the error when using DOMDocument (I thought you were using SimpleXML) "cleanly". You could create a custom PHP error handler for it. Though admittedly that seem rather ugly and I feel PHP really should have made it easier to handle warnings in this case.

I should have used Simple XML. I started this project as a learn PHP project. At least I learned. Thanks for your help Inspire.Rick
