# filter_input_array

(no version information, might be only in CVS)

filter_input_array -- Gets multiple variables from outside PHP and optionally filters them

## Descrição

mixed filter_input_array ( int type [, mixed definition] )

This function is useful for retrieving many values without repetitively calling filter_input().

## Parâmetros

`type`

  One of `INPUT_GET`, `INPUT_POST`, `INPUT_COOKIE`, `INPUT_SERVER`, `INPUT_ENV`, `INPUT_SESSION`, or `INPUT_REQUEST`.

`definition`

  An array defining the arguments. A valid key is a string containing a variable name and a valid value is either a filter type, or an array optionally specifying the filter, flags and options. If the value is an array, valid keys are `filter` which specifies the filter type, `flags` which specifies any flags that apply to the filter, and `options` which specifies any options that apply to the filter. See the example below for a better understanding.

  This parameter can be also an integer holding a filter constant. Then all values in the input array are filtered by this filter.

## Valores de retornado

An array containing the values of the requested variables on success, or `FALSE` on failure. An array value will be `FALSE` if the filter fails, or `NULL` if the variable is not set. Or if the flag `FILTER_NULL_ON_FAILURE` is used, it returns `FALSE` if the variable is not set and `NULL` if the filter fails.

## Exemplos

Exemplo 1. A filter_input_array() example
`<?php error_reporting(E_ALL | E_STRICT); /* data actually came from POST $_POST = array( 'product_id' => 'libgd<script>', 'component' => '10', 'versions' => '2.0.33', 'testscalar' => array('2', '23', '10', '12'), 'testarray' => '2', ); */ $args = array( 'product_id' => FILTER_SANITIZE_ENCODED, 'component' => array('filter' => FILTER_VALIDATE_INT, 'flags' => FILTER_FLAG_ARRAY, 'options' => array('min_range' => 1, 'max_range' => 10) ), 'versions' => FILTER_SANITIZE_ENCODED, 'doesnotexist' => FILTER_VALIDATE_INT, 'testscalar' => array( 'filter' => FILTER_VALIDATE_INT, 'flags' => FILTER_FLAG_SCALAR, ), 'testarray' => array( 'filter' => FILTER_VALIDATE_INT, 'flags' => FILTER_FLAG_ARRAY, ) ); $myinputs = filter_input_array(INPUT_POST, $args); var_dump($myinputs); echo "\n"; ?>`
O exemplo acima irá imprimir:
    array(6) {
      ["product_id"]=>
      array(1) {
        [0]=>
        string(17) "libgd%3Cscript%3E"
      }
      ["component"]=>
      array(1) {
        [0]=>
        int(10)
      }
      ["versions"]=>
      array(1) {
        [0]=>
        string(6) "2.0.33"
      }
      ["doesnotexist"]=>
      NULL
      ["testscalar"]=>
      bool(false)
      ["testarray"]=>
      array(1) {
        [0]=>
        int(2)
      }
    }
