Please read the preliminary notes:
I wrote the following script that I think prints a canonical path without following symbolic links.
It's supposed to work with any filename including space, tabs, carriage return, etc.
Can anyone think of any path that wouldn't resolve to a canonical form with this script?

LEARN ABOUT PHP
is_uploaded_file
IS_UPLOADED_FILE(3) 1 IS_UPLOADED_FILE(3)is_uploaded_file - Tells whether the file was uploaded via HTTP POSTSYNOPSIS
bool is_uploaded_file (string $filename)
DESCRIPTION
Returns TRUE if the file named by $filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried
to trick the script into working on files upon which it should not be working--for instance, /etc/passwd.
This sort of check is especially important if there is any chance that anything done with uploaded files could reveal their contents to
the user, or even to other users on the same system.
For proper working, the function is_uploaded_file(3) needs an argument like $_FILES['userfile']['tmp_name'], - the name of the uploaded
file on the client's machine $_FILES['userfile']['name'] does not work.
PARAMETERS
o $filename
- The filename being checked.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
is_uploaded_file(3) example
<?php
if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
echo "File ". $_FILES['userfile']['name'] ." uploaded successfully.
";
echo "Displaying contents
";
readfile($_FILES['userfile']['tmp_name']);
} else {
echo "Possible file upload attack: ";
echo "filename '". $_FILES['userfile']['tmp_name'] . "'.";
}
?>
