RE: [PHP] populate form input option dropdown box from existing data

Yeah, I used to write that way but found I and others in the team saved a
lot more time troubleshooting and extending the code when returning 6 months
later if it was more verbose. Horses for courses, I guess.

Also, the selected attribute should be selected='selected' to validate
correctly as xhtml. By the same token, looking back at my example, I notice
the multiple attribute of the select should be multiple='multiple' -
apologies for missing that the first time =o)
