 $file = 'C:\Documents and Settings\Michael\Escritorio\Elvis\test.txt';

file_exists($file)
and
file_exists('"'.$file.'"')

both return false although the file does exist on the user's machine.

What am I doing worng?

Kind regards,

Jan Nordgreen

 I have been told that file_exists() looks for files on the server, not
on the user's machine.

If that is correct the question then is: how do I check if a file
exist on the user's machine? Or can't it be done?

Kind regards,

Jan Nordgreen

That'd be up to the possibly-faulty implementation of /Java(script)?/.

Java (applets) can, I suspect Flash can too, javascript only if a
particular UA manufacturer has erred beyond believe.

I'm curious. How does type="file" work? That allows a directory search
of the user's machine. Of course, it it totally under the user's
control, so no security breach, but what mechanism is used to get the data?
