input_get_args

(no version information, might be only in CVS)

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

Description

mixed input_get_args ( array definition, int type [, array data] )

Warning

This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

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

Parameters

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.

type

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

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 if an error occurred.

Examples

Example 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,
                           )

);

//$myinputs = input_get_args($args, INPUT_POST);
$myinputs = input_get_args($args, INPUT_DATA, $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)
  }
}
