Have you tried is_file("/tmp/ >>> secret_file.txt"); to see if it actually exists?

Depends on what app is looking at it. If you have PHP running with Apache and Apache is jailed, the the /tmp folder would be from the perspective to the jail the the actual OS. So, if apache was jailed to /var/www/ you could then have a /tmp/ and a /var/www/tmp/ Apache would never see the /tmp/ only the /var/www/tmp/
