filter_input_array

Description

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

Parameters

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. 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.

Examples

Example 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"; ?> 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) } }
