function shtmlspecialchars($string) {
if(is_array($string)) {
foreach($string as $key => $val) {
$string[$key] = shtmlspecialchars($val);
}
} else {
$string = preg_replace('/&((#(d{3,5}|x[a-fA-F0-9 ]{4})|[a-zA-Z][a-z0-9]{2,5});)/', '&\1′,
str_replace(array('&', '"', '<', '>'), array('&', '"', '<', '>'), $string));
