Model concept (notes)

1. The model is a business model, and the addition, deletion, modification, and query of databases are concentrated in the model,

<? Phpclass test {protected $ table = 'test'; protected $ db = NULL; // public function _ construct () {$ this-> DB = MYSQL :: getins ();} public function Reg ($ data) {// Since the database can be auto_excute, it indicates that the MySQL instance return $ this-> DB-> autoexcute ($ this-> table, $ data, 'insert ');}}

Now we use the test table. If we change the table, we need to re-create _ construct () to create a new model, so we need to create a parent class to inherit from it,
