When you look at PHP you can get to the URL vars in a loop like this
<?php
while ($urlVar = each($_GET))
{
for ($i=0; $i < count($urlVar); ++$i)
{
echo $urlVar["key"]. " item $i = $urlVar[$i]<br>";
}
}
?>
If you wanted to, PHP actually parses URL scoped vars with the same name as
an array, which I think is actually better then the list that CF gives you.
I mean whats easier? ListGetAt(URL.urlVar,2) or URL["urlVar][1]?
Also, PHP actually gives you each item even if the value is empty.
Just say you have this as a URL string
?bla=&bla=&bla=&bla=&bla=
CF will give you URL.bla = ",,,,"
PHP will give you an array of bla but the elements will be empty so you can
go count(@$_GET["bla"]) and it will give you 5.
Do a ListLen(URL.bla) and it will give you 0
This is in PHP 4.0.1 mind you
So there you go
bit of usless info for your friday

You can send form elements as arrays in PHP:
<http://au.php.net/manual/en/faq.html.php#faq.html.arrays>
So:
<select name="foo[]" multiple="multiple">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
Would translate into this in PHP if you selected 'One' and 'Three':
$_POST['foo'][0] = 1;
$_POST['foo'][1] = 3;
