Export contact information to Outlook using PHP

[physics]

I have a database with contact information in it and a PHP app where people can view the contacts and need to make a 'export to Outlook' link. I.e. someone clicks that link next to an entry and, ideally, the information would automatically be imported by Outlook. Is this possible or do I need to have it export to CSV and then have people import it? Thanks.

CSV is the only option... Unless there's an activeX control I'm unaware of.

vCard format might be an option. I would also like to believe that the COM [php.net] could be used to complete the task.

I haven't tried it lately, but I think vCard [google.com] is the way to go.

Thanks, I'll check out the vCard idea... will probably use CSV to allow people to download a whole load of contacts at once though.
