This might sound a bit simplistic, but did you verify if the file
exists via command-line? "ls -l ../myfile"? Also check permissions
on the file, if Apache (or whatever webserver you use) has no
permissions to at least read that file you could return a false on
file_exists() even though the file really does exist (I have run into
that in the past).
