file_exists () seems to get confused with 'hidden' files, starting with '.' (dot).

this works fine:
--------------------------------------------------------------
if(file_exists(test/normal-file)) {
            die ("error message");
    }


this does not work:
--------------------------------------------------------------
if(file_exists(test/.hidden-file)) {
            die ("error message");
    }

Usually we like to have more information than 'doesn't work'. :)
But for the moment, what happens if you quote your strings?

i.e.:

if (file_exists('/file/names/must/be/.quoted.txt')) {
   . . .
}

single quotes works fine. thanks!

also, could be a bug, but i got it to work by having it ~follow~ a symbolic link.

it didn't check that the link existed, it checked the the place the link pointed to existed.
could be a security issue.

thanks... atom

Thats it? And what if i got a hidden file name in a $var?
Since 2001 no fix?
