Hello everyone, happy new year!!
I'm with a doubt, wish you can help me?!. I am developing my website, and it is going to have a multi language system - portuguese, spanish and english, but I don't know how to start, it's gonna hava a dinamic content, where can I get something like tutorials, books, that can help me with my problem. I was think about create many tables, one for each language, when users select a language I create a cookie that has the table name, to make the database querys. what do you think? any suggest?
