You don't need to do
date("Y",$time);sincedate()defaults to the same value astime(). Just dodate("Y");.You don't need to add
strip_tags($input, ""), just write it asstrip_tags($input)since again, the default is "". Also, you should addhtmlspecialchars()sincestrip_tags()will not protect you from XSS attacks.
