thinkphp model Initialization Instance Analysis _php instance

This paper describes the method of thinkphp model initialization. Share to everyone for your reference, as follows:

/*  $dsn = ' mysql://bookman:book123@localhost:3306/weapons ';  $guns _tab = M (' Guns ', ' ', $dsn);  $gun 1 = $guns _tab->select ();  echo $guns _tab-Getlastsql ();  Dump ($gun 1); *//*  $guns _tab = M (' Guns ');  $gun 1 = $guns _tab->select ();  echo $guns _tab-Getlastsql ();  Dump ($gun 1); */  $guns _tab = new Gunsmodel ();  $gun 1 = $guns _tab->select () page (' n ');  echo $guns _tab-Getlastsql ();  Dump ($gun 1);  $guns _tab-Showinfo ();/*  $guns _tab = new Detectmodel (' Guns ');  $gun 1 = $guns _tab select ();  echo $guns _tab-Getlastsql ();  Dump ($gun 1);  $guns _tab-Showinfo (); * *

1. How to connect from a configuration file

$dsn = ' mysql://bookman:book123@localhost:3306/weapons '; $guns _tab = M (' Guns ', ' ", $DSN); $gun 1 = $guns _tab->select () ; Echo $guns _tab-getlastsql ();d UMP ($gun 1);

2. Connect to the database according to the configuration file, the table name must distinguish clearly

$guns _tab = M (' Guns '), $gun 1 = $guns _tab->select (); Echo $guns _tab, Getlastsql ();d UMP ($gun 1);

3. I have a custom model that implements my own business methods, and I have a guns table so that I can initialize the model like this. You can get the data from the guns table, and you can also use the business methods in my custom model.

$guns _tab = new Detectmodel (' Guns '), $gun 1 = $guns _tab, select (), Echo $guns _tab, Getlastsql ();d UMP ($gun 1); $guns _tab, Showinfo ();

It is hoped that this article is helpful to the PHP program design based on thinkphp framework.
