Protect form against XSS attacks

I like to know if there is PHP script to protect forms against XSS attacks.

Need help.

for each form beeing different there is no general solution. you have to implement it the way your project and your tools require it, but you may want to utilize a template engine.

I like to set HTML Filter to prevent XSS attacks. Is there PHP instruction to do this?

look at htmlspecialchars() and htmlentities()

Can you post code?

I believe there is sample code on the PHP documentation site for both of those functions.

Yes, it is good explanation.

There is an article here, it’s a few years old but it should get you started.
