ThinkPHP--ActiveReocrd mode (add, delete, modify, check)

ActiveReocrd mode

The biggest feature of this mode is that it simplifies the operation of CURD and adopts an object-based operation method, which is easy to use
and understand.

//Add a piece of data

$user = M('User');
$user->user = 'Naruto';
$user->email = 'huoyin@qq.com';
$user ->date = date('Y-m-d H:i:s');

$user->add();

//Combined with create

$user = M('User');
$user-> ;create();
$user->date = date('Y-m-d H:i:s');
$user->add();

//Find the value with primary key 4

$user = M ('User');
var_dump($user->find(4));

//Find user=Crayon Shin-chan's record

$user = M('User');
var_dump($user-> ;getByUser('Crayon Shin-chan'));

//Output user

echo $user->user;

//Query multiple

$user = M('User');
var_dump($ user->select('1,2,3'));

//Modify a piece of data

$user = M('User');
$user->find(1);
$user-> ;user = 'Crayon Old New';
$user->save();

//Delete the currently found data

$user = M('User');
$user->find(11);
$user->delete();

//Delete data with primary key 10

$user = M('User');
$user->delete(10);

//Delete data with primary key 10 ,11 data

$user = M('User');
$user->delete('10,11');

The above introduces the ThinkPHP--ActiveReocrd mode (add, delete, modify and check), including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
