Hackers use Multiple XSS attacks, and PHP built-in functions cannot cope with various XSS attacks. Therefore, filter_var, mysql_real_escape_string, htmlentities, htmlspecialchars, strip_tags and other functions cannot be used for 100% protection. You need a better mechanism. Here is your solution: Function xss_clean ($ data){// Fix entity \ n;$ Data = str_replac

Recognized ports are also known as common ports, with a port number of 0-1023, and they are tightly bound to special services and can no longer redefine his object.
