I am using this code:
$text=preg_replace('/\W/', ' ', $body); // strip all punctiation and non-word characters

But have come to realize that I need to keep the hyphens.

What is the easiest way to srtip all non-word characters except the hyphen?
Is there a way to make an exception for "-" while using \W, or some other direct way of doing it?

I figured it out. Thanks anyhow.
I changed it to:
$text=preg_replace('/[^A-Za-z0-9-]/', ' ', $body); // strip all punctuation and non-word characters

Could have also used /[\W-]/
