simplexml_load_file not working “php_network_getaddresses: failed: Name or service not known”

问题

I started getting these warnings just recently, im not sure why, nor do i know how to fix it. What confuses me more, it was working before, i started working on another class and now i starting getting this error...

im using linux fedora & apache for the webserver.

You have a network/DNS problem, not a PHP problem. Seems your machine cannot resolve the IP of api.flickr.com.

"su" to your web server user and try to resolve the name there, i.e.

$ sudo bash
  # get root
$ su - apache
  # we're the apache user now
$ ping api.flickr.com
