为什么file_get_contents()似乎与curl_exec()具有相同的访问权限?

I am downloading favicons using PHP and I spent a while troubleshooting before I noticed that curl_exec appears to work for some sites while file_get_contents does not.

For example here is the response from http://www.hellmanns.com/favicon.ico

file_get_contents

Warning: file_get_contents(http://hellmanns.com/favicon.ico): failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden in /home/arcmarks/public_html/arcmarks/source/class.FaviconFinder.php on line 44

curl_exec

    curl_exec is based upon and entire project that is used in many different languages see here:

    Why doesn't file_get_contents() appear to have the same access as curl_exec()?

    Hence it has much more support.
