I replace any non alpha chat with a hyphen, then replace two or more hyphens with one. Simple, but I would also include the date so that naming clashes are less likely (if it's applicable). So you might end up with something similar to this: /product/2009/06/03/24ct-gold-earrings Or if using the date is not applicable, you could get something like this: /product/24ct-gold-earrings -- Richard Heyes HTML5 graphing: RGraph (www.rgraph.net - updated 23rd May) PHP mail: RMail (www.phpguru.org/rmail) PHP datagrid: RGrid (www.phpguru.org/rgrid) PHP Template: RTemplate (www.phpguru.org/rtemplate) PHP SMTP: http://www.phpguru.org/smtp -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
