This looping function below is useful to disable html in user generated content (message board
posts, webpage-based chat clients, etc). And, so far, it's worked fine alone for sanitizing
user input for database storage. "htmlize_text" here preserves keys and works on
recursive arrays.
<?php
$_GET = htmlize_text($_GET);
$_POST = htmlize_text($_POST);
function htmlizeArray(&$txtArray) {
if (is_array($txtArray)) {
foreach ($txtArray as $key => $val) {
htmlizeArray($val);
}
}
else {
htmlentities($txtArray);
}
}
?>
