ThinkPHP -- ActiveReocrd mode (add, delete, modify, and query)

: This article mainly introduces ThinkPHP -- ActiveReocrd mode (add, delete, modify, and query). If you are interested in PHP tutorials, refer to it. ActiveReocrd mode

This mode simplifies CURD operations and adopts an object-based operation mode for ease of use.
And understanding.

// Add a data entry

$ 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 of primary key 4

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

// Search for user = crayon records

$ User = M ('user ');
Var_dump ($ user-> getByUser ('crayon SHIN '));

// Output the user

Echo $ user-> user;

// Query multiple primary keys

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

// Modify a data record

$ User = M ('user ');
$ User-> find (1 );
$ User-> user = 'crayons old new ';
$ User-> save ();

// Delete the currently found data

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

// Delete data with a primary key of 10

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

// Delete data with a primary key of 10 or 11

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

The above introduces ThinkPHP -- ActiveReocrd mode (add, delete, modify, and query), including some content, and hope to be helpful to PHP tutorials.
