What php/server settings might prevent simplexml_load_file() from working?

I'm using simplexml_load_file() to grab the contents of an RSS feed: 

$rss = simplexml_load_file('http://www.iolproperty.co.za/roller/news/feed/entries/rss');

This works as expected on my local server but fails silently when deployed to my client's production server, returning an empty result.

The phpinfo() function says that SimpleXML support is enabled, and it does seem that I'm allowed to access remote files (cURL functions work just fine). I've also tried loading different RSS feeds. Again, they work locally but return empty when deployed.

A production server might have outgoing internet request blocked to prevent abuse. Another reason could be that its a different PHP version or some mods are not included in the configuration. Use error reporting to see the error message

error_reporting(E_ALL);

//UPDATE

You could also check if you get a value back from the server like 

$c = implode('', file('http://www.iolproperty.co.za/roller/news/feed/entries/rss'));
print $c;
$rss = simplexml_load_string($c);

and check what the others are saying, check if allow_url_fopen option is enabled

simplexml_load_file need that allow_url_fopen directive is enabled in php.ini if you want to load an external file. Curl functions does not need this directive, so it works for you.

You have to set allow_url_fopen option enabled for that to work.
