I just upgraded one of my servers to 4.0.5, and am having a problem where any attempt to fopen a PHP file on that server via HTTP will fail.

From another (4.0.4pl1 on Unix) PHP server if I try the following code:

$handle = fopen("http://405host/phpinfo.php", "r");

I get the following error (and fopen returns false):

Warning: fopen("http://405host/phpinfo.php","r") - Inappropriate ioctl for device in /path/read.php on line 8

If I try the same code from the 4.0.5 server, or from a 4.0.4pl1-on-NT server, fopen returns false with the following error message:

Warning: fopen("http://405host/phpinfo.php","r") - No error in E:\Inetpub\wwwroot\read.php on line 8

If I try the same code and attempt to open a plain HTML file or an ASP file, everything works fine. It's only when trying to open a PHP file that these mysterious errors occur.

I also have a ASP component that opens an HTTP connection to a URL and prints the returned HTML. This component also can no longer access any PHP files on the 4.0.5 server.
