What is the value for
"allow_url_fopen<http://www.php.net/manual/en/filesystem.configuration.php#ini.allow-url-fopen>"
in your php.ini? It should be 1.

Do you have a default stream context defined for the http stream?

A _LONG_ time ago, when I was using a firewall with NTLM
authentication (which PHP doesn't deal with), I had to route all my
calls through a local proxy.

This was the code I had ...

<?php
// Define the default, system-wide context.
$r_default_context = stream_context_get_default(
array(
'http' => array( // All HTTP requests are passed through the local
NTLM proxy server on port 8080.
'proxy' => 'tcp://127.0.0.1:8080',
'request_fulluri' => True,
),
)
);

// Though we said system wide, some extensions need a little coaxing.
libxml_set_streams_context($r_default_context);


Now, you may not see this in your code, but may be in a script which
is loaded via auto_prepend_file.

I would also suggest running something like WireShark at the same time
as your script. See if there is ANY traffic over the wire.

Do the cURL and file_get_contents() code generate identical requests?

But by using something like WireShark you can see exactly what
requests ARE being made. You may be getting a redirect reply which is
failing or something daft. Anything really.
