如何检查RSS供稿是否正常工作？

Question

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!

Answer 1

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

An example can be found here

Answer 2

You can do this:

error_reporting(E_WARNING);

if (!$xmlDoc->load($url)){ 

 echo ("Not content could be loaded.");

}
