Then access it through the browser. I get: IUSR_MACHINE, the Internet Guest Account on Windows, which is certainly not the owner of the script.
On Centos, the Red Hat linux clone, this instruction gives the file's OWNER (the first parameter in instruction 'chown'). It does not reveal the file's GROUP.
get_current_user() does NOT reveal the current process' user's identity.
