PHP nav bar

[Aaron]

I am making a nav bar that identifies what directory and file the user is
on. If in a certain directory a block of links show up relating to the
directory. If not they are not there.

The problem I am having: I am using one function that is given a different
variable from each block, and I want to determine if the function returns
true or passes for each variable. Does anyone have an idea?

Why does it need to be so complex? Why notjust check the directory then
display the proper code if the directory matches?

if($_SERVER['PHP_SELF'] == "/ds/") {
echo " ..." }
elseif($_SERVER['PHP_SELF'] == "/fg/") {
etc, etc...
