filter_var_array

Description

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

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.

Examples

Example 1. A filter_var_array() 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_FORCE_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_REQUIRE_SCALAR,                            ),     'testarray'    => array(                             'filter' => FILTER_VALIDATE_INT,                             'flags'  => FILTER_FORCE_ARRAY,                            ) ); $myinputs = filter_var_array($data, $args); var_dump($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) } }
