Die if file not found

[sssweb]

How do I tell a script to die if no file is found, where the file is defined as $page.

[vevs]

something like this should do it
if (is_file('path_to_file_and_file_name')) {

} else {
die("no such file");
};

Thanks, that worked. I added a command to send an email to the site admin before it dies; I want to include the page with the bad link - what would be the $string for the current page?

[vevs]

try this
$_SERVER['REQUEST_URI'];

[sssweb]

I got a parse error; the context I'm using it in is this:

mail( $email, "Subject",
"Message - $_SERVER['REQUEST_URI']; ",
"From: Sender <$email>" );

[vevs]

mail( $email, "Subject",
"Message - ".$_SERVER['REQUEST_URI'],
"From: Sender <$email>" );

[sssweb]

Thanks -- that did it.
