I think it is better to populate everything as string, and let the application developer to parse the inputs as he knows what should they represent. Btw. there was a discussion about raising a warning (somebody even suggested creating an E_TYPE level) when data loss occurs on a type juggling. I would support that, as people tend to be surprised when they realize the first time that 123 == '123 apples' evaluates to true in php. -- Ferenc Kovács @Tyr43l - http://tyrael.hu
