# filter_list

(no version information, might be only in CVS)

filter_list -- Returns a list of all supported filters

## Beschreibung

array filter_list ( void )

## Rückgabewerte

Returns an array of names of all supported filters, empty array if there are no such filters. Indexes of this array are not filter IDs, they can be obtained with filter_id() from a name instead.

## Beispiele

Beispiel 1. A filter_list() example

`<?php print_r(filter_list()); ?>`

        [2] => float
        [3] => validate_regexp
        [4] => validate_url
        [5] => validate_email
        [6] => validate_ip
        [7] => string
        [8] => stripped
        [9] => encoded
        [10] => special_chars
        [11] => unsafe_raw
        [12] => email
        [13] => url
        [14] => number_int
