How to use the Hyperf framework for data migration

Introduction:
Data migration is an important part of modern software development, used to manage database structure and data Variety. The Hyperf framework provides a simple yet powerful way to handle data migration. This article will introduce in detail how to use the Hyperf framework for data migration and provide specific code examples.

1. Overview
The Hyperf framework provides a component named PhperDbMigrate for handling data migration operations. It is based on the Phinx library and can easily manage structural changes in the database, thereby ensuring data consistency and reliability of the application. The following will introduce how to use the PhperDbMigrate component for data migration in the Hyperf framework.

2. Installation and configuration
Before using the PhperDbMigrate component, you need to install and configure it in the Hyperf project. First, use the Composer command to install the component:

composer require phper/migrate --dev

Then, add the @AutoAnnotationProcessor annotation in the config/autoload/annotations.php file:

<?php
return[
    'Scan' => [
        // ...
        'ignore_annotations' => [
            // ...
            PhperMigrateAnnotationsAutoAnnotationProcessor::class
        ],
    ],
    // ...
];

Finally, use the following command to generate the migration configuration file and directory:

php bin/hyperf.php migrate:init

3. Create a migration file
Use the following command to create a migration file:

php bin/hyperf.php migrate:create create_users_table

The generated migration file is located in ## In the #migrations directory, the file name is similar to 20220208123456_create_users_table.php. Modify the file and fill in the corresponding up and down methods, for example:

<?php
declare(strict_types=1);

use PhperMigrateAbstractMigration;

class CreateUsersTable extends AbstractMigration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        $this->schema->create('users', function (HyperfDatabaseSchemaBlueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        $this->schema->drop('users');
    }
}

$this->schema->create() method to create a users table, and defines the id, name, email and timestamps fields. In the down method, we delete the table using the $this->schema->drop() method.

Use the following command to perform the migration operation:

php bin/hyperf.php migrate:migrate

users table will be created in the database.

Use the following command to rollback the migration operation:

php bin/hyperf.php migrate:rollback

users table in the database will be deleted.

This article introduces how to use the Hyperf framework for data migration and provides specific code examples. Through the PhperDbMigrate component, we can simplify the data migration process and easily manage database structure and data changes. I hope this article is helpful to you, and I hope you can better use the Hyperf framework for development.
