How to upgrade laravel version

Laravel is a very popular PHP web application development framework. The Laravel team releases new versions every few months, so it is very important to upgrade to the latest version to maintain the security and functionality of the framework.

Here are the steps on how to upgrade your Laravel application.

1. Back up the project

Before upgrading, be sure to back up the entire project folder (including database and configuration files) to prevent data loss in the event of a mistake.

2. Check the current version

Before upgrading Laravel, you need to know your current version. You can check your Laravel version by running the following command in the command line:

php artisan --version

In the output, you will see the version number of Laravel. For example: Laravel Framework 5.8.38

3.Update Laravel

There are two options to update Laravel: manually and using Composer.

Updating Laravel manually requires you to download the latest Laravel files and overwrite them into your project folder. This method is more troublesome, and it is recommended to use Composer to upgrade.

Updating Laravel using Composer is very simple. Just open a terminal or command line, go into the project folder and run the following command:

composer update

This will update Laravel and its dependencies.

4. Change the configuration file

After upgrading the Laravel version, you need to change the configuration file. Open the app.php file in the config folder and replace the following lines of code with the Laravel version number you are currently using:

'locale' => 'en',
'timezone' => 'UTC',
'faker_locale' => 'en_US',
'key' => env('APP_KEY'),
'cipher' => 'AES-256-CBC',

Please note that this is in English as an example, you need to replace it with your own language used.

5. Update development dependencies

If you are using Laravel Mix or other front-end tools, please remember to update development dependencies. Running the following command will update all development dependencies:

npm update

6. Run database migration

If your project uses the Laravel database migration function, please remember to run the migration to upgrade the database. Run the following command to upgrade the database:

php artisan migrate

7. Run static file publishing

If your project uses the Laravel static file publishing function, please remember to run static file publishing. Run the following command to run static file publishing:

php artisan storage:link

8. Verify the upgrade

After upgrading, make sure your application does not encounter errors. You can test your application in a local environment or using a test environment.

Conclusion

Upgrading Laravel is not difficult, just follow the above steps. Upgrading to the latest version is important as it will make your application more secure and run better. However, after the upgrade is complete, be sure to test your application to ensure it does not run into errors.
