New code for stripping tags from form input. The reason for the addition is that the original code
gave me trouble when trying to pass arrays via a form. This seems to fix the problem:

if(is_array($HTTP_POST_VARS)) {
reset($HTTP_POST_VARS);
while (list($key, $val) = each($HTTP_POST_VARS)) {
if (is_array($val)) {
while (list($akey,$aval) = each($val)) {
$HTTP_POST_VARS[$key][$akey] = strip_tags($aval);
$$key[$akey] = strip_tags($aval);
}
} else {
$HTTP_POST_VARS[$key] = strip_tags($val);
$$key = strip_tags($val);
}
}
}
if(is_array($HTTP_GET_VARS)) {
reset($HTTP_GET_VARS);
while (list($key, $val) = each($HTTP_GET_VARS)) {
if (is_array($val)) {
while (list($akey,$aval) = each($val)) {
$HTTP_GET_VARS[$key][$akey] = strip_tags($aval);
$$key[$akey] = strip_tags($aval);
}
} else {
$HTTP_GET_VARS[$key] = strip_tags($val);
$$key = strip_tags($val);
}
}
}
if(is_array($HTTP_COOKIE_VARS)) {
reset($HTTP_COOKIE_VARS);
while (list($key, $val) = each($HTTP_COOKIE_VARS)) {
if (is_array($val)) {
while (list($akey,$aval) = each($val)) {
$HTTP_COOKIE_VARS[$key][$akey] = strip_tags($aval);
$$key[$akey] = strip_tags($aval);
}
} else {
$HTTP_COOKIE_VARS[$key] = strip_tags($val);
$$key = strip_tags($val);
}
}
}
