title: how to prevent textbox php script coding?
body: <p>I have this comment box and every comment of the user I get the contents of the comment and insert it to database. But whenever there's some destructive user that will enter  or  alert('Hello World'); . It was detected and it creates  abnormalities to the website. How can I prevent this issue? or how to ignore the function of that "TEXT" as a script. Thanks!</p>
