Dealing With User Entering a Script

[Stephen <stephen-d@xxxxxxxxxx>]

I dug back to see where I git the idea of using htmlentities() on user 
input.

This came from the book Modern PHP and deals with a user entering in a 
text box something like:

<script>window.location.href='http://example.com';</script>

Is there a better way of dealing with this?


For context, I am creating a user registration field and there is a 
textarea field for their bio.

Thank you!
