filter_list

    (PHP 5 >= 5.2.0, PHP 7, PHP 8)

    filter_list — 返回所支持的过滤器列表

    说明

    filter_list(): array

    参数

    此函数没有参数。

    返回值

    返回一个所支持的过滤器的名称的列表，如果没有这样子的过滤器的话则返回空数组。这个数组的索引不是过滤器id， 你可以通过 filter_id() 去根据名称获取它们。

    示例

    示例 #1 一个 filter_list() 的例子

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

    以上示例的输出类似于：

    Array
(
    [0] => int
    [1] => boolean
    [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
    [15] => number_float
    [16] => magic_quotes
    [17] => 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
