Encrypting a Telephone Number

I don't see a script here, I am assuming it'd be javascript, like the the script you have for encrypting an email address

What I want it to do is to display the phone number in the Web browser but encrypt the number so that a spambot couldn't find the telephone number.

Does anything like this exist on your site. I searched but can't find it.

Thanks

You could use PHP gb library to generate the number into a picture.

But JS isnt a good way to go about encryption, once the js is excecuted, all the spambot has to do is veiw the current source.
