    Get filter_list() with filter_id() as key.

    <?php
    print_r    (array_flip(array_map('filter_id', array_combine(filter_list(), filter_list()))));
    ?>

    Array
    (
    [257] => int
    [258] => boolean
    [259] => float
    [272] => validate_regexp
    [277] => validate_domain
    [273] => validate_url
    [274] => validate_email
    [275] => validate_ip
    [276] => validate_mac
    [513] => stripped
    [514] => encoded
    [515] => special_chars
    [522] => full_special_chars
    [516] => unsafe_raw
    [517] => email
    [518] => url
    [519] => number_int
    [520] => number_float
    [521] => magic_quotes
    [1024] => callback

    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
