function protect( $str )
{
if( !is_array( $str ) ) {

$str = preg_replace("/(from|select|insert|delete|where|drop table|show tables)/i","",$str);
$str = preg_replace('~&#x([0-9a-f]+);~ei', 'chr(hexdec("\\1"))', $str);
$str = preg_replace('~&#([0-9]+);~e', 'chr("\\1")', $str);
$str = str_replace("<script","",$str);
$str = str_replace("script>","",$str);
$str = str_replace("<Script","",$str);
$str = str_replace("Script>","",$str);
$str = trim($str);
$tbl = get_html_translation_table(HTML_ENTITIES);
$tbl = array_flip($tbl);
$str = addslashes($str);
$str = strip_tags($str);
return strtr($str, $tbl);
