Problem using simplexml_load_file to access service

[sn_pst]

Hi,

I'm learning PHP and trying to learn how to call a service .
I try to use the simplexml_load_file but it doesn't work (it always returns false -- code below). I did some research and found that allow_url_fopen in php.ini should be "on" but it doesn't solve the problem.

Code: Select all

$xml = simplexml_load_file('http://finance.yahoo.com/rss/headline?s=lvs'); 
 
if ( $xml == false ) 
echo "something wrong when parsing xml."; 

I do testing in my local windows Vista machine using XAMPP.
Thanks in advance for the help.

If you want to check against boolean values (TRUE or FALSE), the Integers 0 or 1 or the strings "0" or "1" you should always use === instead of ==. Otherwise the php interpreter tries to check if any of the check values match.
It helps too to check for the variable type or in your case to check if is_object($xml), because simplexml_load_file returns an object on success
