Sample code:

$html = file_get_contents('http://www.google.com');
echo $html;

It works on localhost. But after uploading to the webserver, it gives me a warning: file_get_contents(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution. If I replace the domain name with google's IP address, it gives a warning: failed to open stream: Connection timed out.

And ini_get("allow_url_fopen") return 1.
