 $str = Preg_replace ("/&/i", "&", $STR);
 $str = Preg_replace ("/</i", "<", $str);
 $str = Preg_replace ("/</i", "<", $str);
 $str = Preg_replace ("/"/I ", '" ", $str);
 $str = Preg_replace ("/&ldquo/i", "" ", $str);
 $str = Preg_replace ("//I", "'", $str); $str = Preg_replace ("/&lsquo/i "," ' ", $str);
 $str = Preg_replace ("//I", "'", $str);
 $str = Preg_replace ("/&rsquo/i", "'", $str);
 $str = Preg_replace ("/>/i", ">", $str);
 $str = Preg_replace ("/>/i", ">", $str);
 $str = Preg_replace ("/"/I ", '" ", $str);
 $str = Preg_replace ("/&rdquo/i", "" ", $str);
 $str = Strip_tags ($STR);

 }
