file_exists for remote files

Does anyone know a workaround for file_exists with remote (HTTP) files. I
couldn't file one at php.net or google.

You can use fopen() to test if a URL exists.

Use of file_exists() on a remote file makes no sense, since the "file"
will ALWAYS exist in the sense that you will ALWAYS receive some kind
of file-like data back. The remote HTTP server will either give you
the file if it exists and is available or return an HTTP error message
(404 Not Found, 403 Forbidden, 500 Server error, etc.) The only case
when you don't receive a response is when the remote server is down.

can you give an exemple of your use of the function file_exists with remote
(http) files

Hmm... I think I didn't communicate clearly enough... file_exists()
CANNOT be used on remote files, and there is a good reason for that
which I thought I explained...
