<?php
if (isset($selected)){
$selected_list = implode(', ', $selected);
$where = " where not id in ($selected_list) ";
}
else{
$where = '';
}
$query = "select id, whatever from blah $where ";
$choices = mysql_query($query) or die(mysql_error());
echo "<SELECT NAME=selected>\n";
while (list($id, $whatever) = mysql_fetch_row($choices)){
echo "<OPTION $id>$whatever</OPTION>\n";
}
echo "</SELECT>\n";
?>
>2. I have created a session variable $session. This is an array. I have a

It would probably be easier to just make a 2-D array instead of dealing with
variable variables...
>3. This is similar to above, but it refers to functions. Is it possible to

You can *call* a variable-named function, but I don't think you can define
them like that...
