How thinkphp saves database

In web application development, the database is a vital component as it stores all the critical data in the application. thinkphp is a widely used PHP framework that provides functions to access and operate MySQL databases conveniently and quickly. In this article, we will discuss how thinkphp saves databases.

First, we need to define our database table using the model in thinkphp. A model is a PHP class that represents a database table and allows us to manipulate the database table using PHP code. Create a new User.php file in the model directory:

<?php namespace app\model;

use think\Model;

class User extends Model
{
    //定义表名
    protected $table = "user";
}

In the User model, we map our database table by defining the table name "user". Next, we can use the model to manipulate our database tables. Here is an example of saving data into a database table:

use app\model\User;

$user = new User;
$user->name = 'John';
$user->email = 'john@example.com';
$user->save();

The above code creates a new user named "John" with an email of "john@example.com" and saves it into our database table.

In addition to using models, we can also use the DB class to operate the database. The DB class is a built-in class in thinkphp that provides a very simple interface to handle database connections and operations. Here is an example of using the DB class to save data into a database table:

use think\facade\Db;

$data = [
    'name' => 'John',
    'email' => 'john@example.com'
];
Db::table('user')->insert($data);

The above code creates a new user named "John" with an email of "john@example.com" and Insert it into our database table.

Whether we are using a model or a DB class, we can use the save method to save data to our database table. The save method will automatically insert or update data into the corresponding database table based on the properties we set.

To summarize, thinkphp provides a variety of methods to save data to the database. Whether using models or DB classes, they all have similar interfaces and operations. Using models is more intuitive and object-oriented, while using DB classes is simpler and more flexible. Which method to choose depends on the needs of the project and the preferences of the developer.
