This function is useful for retrieving a large amount of values without repetitively calling input_get().

## Parameters

type

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

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.

data

  Data to filter. Used if the type parameter is set to `INPUT_DATA`.

## Return Values

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.

範例 1. A input_get_args() example

`<?php
error_reporting(E_ALL | E_STRICT);
$data = 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 = input_get_args(INPUT_POST, $args);
$myinputs = input_get_args(INPUT_DATA, $args, $data);
var_dump($myinputs);
echo "\n";`

The above example will output:

    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)
      }
    }
