(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] )

Atenção

Esta função é EXPERIMENTAL. Isso quer dizer que o comportamento desta função e seu nome, incluindo TUDO o que está documentado aqui pode mudar em futuras versões do PHP, SEM QUALQUER NOTIFICAÇÃO. Esteja avisado, e use esta função por sua própria conta e risco.

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 is 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)
  }
}
