2 strings, but it's faster (-2 calls) and not the longest
<?php
$filters = filter_list();
$filters = array_combine($filters, array_map('filter_id', $filters));
?>
also I use id's as values: $filters[$filter] - get filter id by name

Output a table of Filter IDs as Integers with corresponding Constant IDs:
<?php
echo '<table>';
echo '<tr>';
echo '<th>Filter Name</th>';
echo '<th>Filter Int ID</th>';
echo '<th>Filter Const ID</th>';
echo '</tr>';
foreach (filter_list() as $id =>$filter) {
$const = 'FILTER_';
switch($filter) {
case 'int':
case 'boolean':
case 'float':
$const .= 'VALIDATE_' . $filter;
break;
case 'string':
case 'stripped':
case 'encoded':
case 'special_chars':
case 'full_special_chars':
case 'unsafe_raw':
case 'email':
case 'url':
case 'number_int':
case 'number_float':
case 'magic_quotes':
$const .= 'SANITIZE_' . $filter;
break;
}
if (substr($filter,0,8)=='validate' || $filter=='callback')
$const .= $filter;
echo '<tr><td>' . $filter . '</td><td align="center">' . filter_id($filter) . '</td><td>' . strtoupper($const) . '</td></tr>';
}
echo '</table>';
?>
