Re: [PHP] Logic headache, please help.
How about building an array of all the levels:
$a = array();
for ($i = 1; $i = $maxlevels; $i++)
$a[] = $i;
then for each level you can create a new array that is the difference
between the original array and an array that contains the current level:
for ($i = 1; $i = $maxlevels; $i++)
$a1 = ;
echo 'option value=' . implode ('|', array_diff ($a, array($i))) .
'Level ' . $i;
I'm not 100% that this will work right off the bat, but it should at
least put you on the right track... if not out of your misery :-)
Hope this helps.

Hi all,
brief explanation:
I'm building a select list, to exclude certain directories from a search
(with Ht://dig).
The structure is like this:
select name=exclude
option value=All levels/option
option value=/lv2/|/lv3/|/lv4/Level 1/option
option value=/lv1/|/lv3/|/lv4/Level 2/option
option value=/lv1/|/lv2/|/lv4/Level 3/option
option value=/lv1/|/lv2/|/lv3/Level 4/option
/select
for four levels, where the option value should be all lv's except the
current option level.
I have a variable $maxlevels to count up to however many levels are
required and I want to make this select list work based on the value of
$maxlevels.
How would you approach the building of the list?
I was going to use a while loop or two, but I'm stuck at the point of
creating the value string which should contain all the levels from 1
to $maxlevels except the current level. which would seem to require some
sort of conditional if $thislevel string is type of approach, but I
can't get my head round it.
Anyone put me out of my misery?
Thanks
Tony

It looks like it might, but I note this warning in the manual
re:array_diff
Warning
This was broken in PHP 4.0.4!
http://www.php.net/manual/en/function.array-diff.php
is it fixed in 4.06 do you know? (host uses 4.06, I have 4.2.2)
TIA

My guess is it works... but only one way to find out--try it! :-)
