How to use the Hyperf framework for ORM mapping
Introduction:
The Hyperf framework is a high-performance framework based on Swoole and PHP7. Through the reasonable use of ORM (object Relational mapping) can improve code readability and maintainability. This article will introduce how to use the Hyperf framework for ORM mapping and provide detailed code examples.
- Configuring the database connection
In the Hyperf framework, we need to first configure the database connection. Open the config/autoload/database.php file and fill in the database configuration information in the connections array. For example, we use a MySQL database with the following configuration:
'connections' => [
'default' => [
'driver' => 'mysql',
'host' => 'localhost',
'port' => 3306,
'database' => 'test',
'username' => 'root',
'password' => '',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
],- Create model
In the Hyperf framework, we can use command line tools to quickly create model files. Open the terminal, enter the project root directory, and execute the following command:
php bin/hyperf.php gen:model Test --table=test
The above command will generate a model file named Test in the app/Model directory, and the corresponding data table is test.
- Define the model
Open the app/Model/Test.php file, we can see the following:
<?php
declare (strict_types=1);
namespace AppModel;
use HyperfDbConnectionModelModel;
class Test extends Model
{
/**
* The table associated with the model.
*
* @var string
*/
protected $table = 'test';
}In the model class, we can define with Properties and methods corresponding to the data table. For example, we can define a scopeQuery method to build complex query conditions:
public function scopeQuery(Builder $query, array $conditions): Builder
{
return $query->where('column1', $conditions['column1'])
->where('column2', '>', $conditions['column2']);
}- Data operation example
Next, we can perform database operations through the model. The following are examples of some common operations:
- Query a single piece of data:
$data = Test::find(1);
- Query multiple pieces of data:
$datas = Test::whereIn('id', [1, 2, 3])->get();- Insert data:
$data = new Test(); $data->column1 = 'value1'; $data->column2 = 'value2'; $data->save();
- Update data:
$data = Test::find(1); $data->column1 = 'new_value1'; $data->column2 = 'new_value2'; $data->save();
- Delete data:
$data = Test::find(1); $data->delete();
- Use the scopeQuery method to query:
$conditions = [
'column1' => 'value1',
'column2' => 10,
];
$data = Test::query($conditions)->get();In addition to the above examples, the Hyperf framework also supports more advanced query and operation methods. You can find more information in the official Hyperf documentation.
Summary:
Using the Hyperf framework for ORM mapping can greatly simplify database operations and improve the readability and maintainability of the code. Through the introduction of this article, you can learn how to configure database connections, create models, define models, and perform common data operations. I hope this article will help you use ORM mapping in the Hyperf framework. For more complex application scenarios, you can refer to Hyperf official documentation for in-depth study.
