A good point, but in this application there WILL be AT LEAST 1
legitimate directory at all times, or else the script would not be used,
so this ought not be a problem.
My problem is that I understand the basic functions to implement, but
have not yet aquired sufficient command of php to implement the required
multi step algorithm.

Hello all, my name is Kirk Bailey, and I am new to php, so please be forbearing.
I code in python, and am trying to learn this language as our new client runs a
web business based in it.
I need a routine that will return a list of every directory immediately under
the current directory- but nothing else, just a list of directories, 1 level
deep, NO FILES, no listing of current dir or prior dir either.
Now in python, I would use os.walk, and use the list of dirs and throw the other
2 lists away, but this ain't Kansas anymore. Does php even DO lists?
Um, a list is a 1 dimenional array, if have a list ALIST and you plug in 3, you
get back the contents of cell 3 in the list, whaqtever that content is. so if
cell 3 in a 6 celled list was "Ruby" then ALIST[3] would return the string "ruby".
It's easy to iterate lists. For instance:
print '<ul>'
for dir in ALIST:
print '<li><a href=\"/dir>",dir,'</a>
print '</ul>
This would let me produce an ordered list of directories, each a link to that
directory.
This way, when a client installs a new product, the home page area listing
products offered automatically updates.
Further embellishment would let me replace the dir name with a BRIEF description
from a descriptor file read from that dir. Now how to do this in php?
This should do.
The only problem that I foresee would be an empty "<ul></ul>" if you have no
directories returned by glob().
print('<ul>');
foreach ( glob('./*', GLOB_ONLYDIR) AS $dir )
print('<li><a href=\"'.$dir.'\">'.$dir.'</a></li>');
print('</ul>');
