Hvordan tæller jeg dagene fra en oprettelsesdato?

Der er vist ikke nogen standard datoforskel-funktion. Se evt.: http://www.ilovejackdaniels.com/php/php-datediff-function/

eller søg på Google efter "php datediff".

Hvis du bruger MySQL (over v4.1.1), så brug et DATETIME felt og brug mysqls egen DATEDIFF() funktion...

Hmm, har prøvet nogle eksempeler og læst og læst, men af en eller anden grund, så virker det ikke. Det er som om den slet ikke kender funktionen`?

Har du også kopieret selve funktionen ind? ;)

Hmm.. Knap så overskueligt her.

hmm, tror det er fordi min version er for gammel /:

lukker...
