Wich the best way to control the logic of a web application?

[Andre Lopes <lopes80andre@xxxxxxxxx>]

Hi,

Now I'am with some doubts on how to control the logic of a web application?

So... the web application uses PHP, object oriented and PostgresSQL Database. I have developed some procedures and functions in the database but I don't know if it is correct to mix logic in the database and PHP.

What do you think aboout this? Should I mix logic in Database and PHP or should I control the logic only in the PHP?

Best Regards,
André.
