Hi Guys,
Actually what I settled on was:
function is_root() {
if (is_writable('/'))
return TRUE;
if (extension_loaded('posix') && posix_getuid() == 0)
return TRUE;
if (getenv('USER') == 'root')
return TRUE;
return FALSE;
}
But looking at this now I think perhaps
function_exists('posix_getuid') would be better than extension_loaded.
I'll have to change that.
Also, I guess is_writeable('/') isn't fool-proof.
Mike
