Help me finish this...Please!

Hi All,

I've very nearly finished my bread crumb trail script. It picks up the URL,
and then turns it into a bread crumb trail, so the user can always walk back
to where they came from.

I have two problems, which I am struggling with:

1) If the URL is, for example /attractions/Dorset then the trail ens up like
this: 'attractions'. Only when I add a trailing / to the URL does the trail
end up as it should be: 'attractions > Dorset'

2) I always seem to end up with a trailing > sign

My code is below - Any help getting this finished would be appreciated.

Thanks!
Simon.

// Generate Bread Crumb Trail
function genbctrail() {
$arr_bits = explode("/",$_SERVER{'REQUEST_URI'});
$count = count($arr_bits);

for ($i=0; $i < $count-1; $i++) {

$StrHref = $StrHref. $arr_bits[$i]. "/";
$StrLink = "<a href=" .$StrHref. ">" .urldecode($arr_bits[$i]). "</a>";

$countForCompare = $count-1;

// Diags: print $i. " - " .$countForCompare. "<br>";

if ($i > 0 && $i <= $countForCompare) {
// print $i. " - " .$count. "<br>";
$StrLink = $StrLink. " > ";
}

$StrBCTrail = $StrBCTrail. $StrLink;
}
print $StrBCTrail;

}

I've just solved the second problem with the trailing > sign, here is my
updated code:

// Generate Bread Crumb Trail
function genbctrail() {
$arr_bits = explode("/",$_SERVER{'REQUEST_URI'});
$count = count($arr_bits);
$countForCompare = $count-2;

for ($i=0; $i < $count-1; $i++) {

$StrHref = $StrHref. $arr_bits[$i]. "/";
$StrLink = "<a href=" .$StrHref. ">" .urldecode($arr_bits[$i]). "</a>";

if (($i > 0) && ($i <> $countForCompare)) {
$StrLink = $StrLink. " > ";
}

$StrBCTrail = $StrBCTrail. $StrLink;
}
print $StrBCTrail;
}

Would appreciate any ideas or pointers on the first problem.

Regards,
Simon.
