Using fopen to read a URL - DNS Problem?

The following code: $url = "http://www.php.net/"; print ( implode( "", file( $url ) )); causes my browser to sit and twiddle it's thumbs for ages and then produce:

    Warning: file("http://www.php.net/") - Bad file descriptor in myfile.php on line 33

    Warning: Bad arguments to implode() in myfile.php on line 33

If, however, I explictly use the IP address:

    $url = "http://208.247.106.187/";
    print ( implode( "", file( $url ) ));

it will successfully dump a copy of the php front page. This says to me that PHP can't resolve names. It is not a problem with the linux box it's running on, given that I ran "ping www.php.net" on that particular box to find the IP address. Can anyone tell me what I need to do to make it work?
