As a matter of fact there is a function in the URL helper to do this.

url_title()

Takes a string as input and creates a human-friendly URL string. This is useful if, for example, you have a blog in which you'd like to use the title of your entries in the URL. Example:
$title = "What's wrong with CSS?";

Code:

$url_title = url_title($title);
// Produces: whats-wrong-with-css
