PHP -Sanitize values of a array

Just use the filter extension.

/* prevent XSS. */$_GET   = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING);$_POST  = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);

This will sanitize your $_GET and $_POST.

Have a look at array_map

<?php  $a = array('title' => 'Title','data' => array(    'hdr' => 'Header',    'bdy' => 'Body'    ),'foo' => array(1, 23, 65));$b = array_map("strip_tags", $a);print_r($b);?>

Update for 2D array:

function array_map_r( $func, $arr ){    $newArr = array();    foreach( $arr as $key => $value )    {        $newArr[ $key ] = ( is_array( $value ) ? array_map_r( $func, $value ) : ( is_array($func) ? call_user_func_array($func, $value) : $func( $value ) ) );    }    return $newArr;}

Usage:

$a = array('title' => 'Title','data' => array(    'hdr' => 'Header',    'bdy' => 'Body'    ),'foo' => array(1, 23, 65)); $ar =array_map_r('strip_tags', $a);print_r($ar);

Note I found this just by searching the comments for Dimension

function strip($string, $allowed_tags = NULL){    if (is_array($string))    {        foreach ($string as $k => $v)        {            $string[$k] = strip($v, $allowed_tags);        }        return $string;    }    return strip_tags($string, $allowed_tags);}

Just an example of a recursive function, for stripping tags in this case.

$arr = strip($arr);
