sean commented on a Page, htmlspecialchars() for arrays / nested arrays - May 03, 2012

Great example @Typo !
You could also look into using array_walk_recursive. Consider the following:

<?php

function _clean(&$value) {
  $value = htmlspecialchars($value);
}

$a = array(
  1 => '<script />',
  2 => '<div bla="bla&bla2=morebla"',
  3 => array(
    1 => '<script />',
    2 => '<div bla="bla&bla2=morebla"',
  ),
);

array_walk_recursive($a, '_clean');
printf('<pre>%s</pre>', print_r($a, 1));

?>

This route makes things a bit easier if you need add more data cleaning methods :)
