SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for db failed: No such host is known. (Connection: mysql, SQL: select * from `sessions` where `id` = vWIPUy9vd3R9kRNAAgN8SEK8TX793LoJNEKI1eo0 limit 1)

1. **Check Docker Service Names**: Ensure that the MySQL service name in `docker-compose.yml` matches the database host configuration in your Laravel `.env` file. For example, if your MySQL service is named `mysql` in `docker-compose.yml`, your `.env` file should have:
DB_HOST=mysql
Update `DB_HOST` if necessary to match the exact service name.
2. **Check Network Configuration**: Make sure all services are connected to the same Docker network, especially the Laravel app and the MySQL service. In your case, they should all be on the custom network `shareyourthoughts_shareyourthoughts_laravel`.
3. **Rebuild Containers**: Sometimes, rebuilding the containers helps resolve networking issues. Run:
docker-compose down
docker-compose up --build
4. **Check MySQL Service Logs**: Run the following to check if the MySQL service is running correctly and without errors:
docker-compose logs mysql
5. **Test Database Connection**: Verify that the Laravel application can connect to the database using `artisan`:
php artisan migrate
These steps should help resolve or identify the root cause of the `php_network_getaddresses` error. Let me know if the issue persists after trying these steps.
1. **Verify Database Host**: In XAMPP, the MySQL server host is usually `127.0.0.1` or `localhost`. Check your `.env` file in the Laravel project and set the `DB_HOST` to `127.0.0.1`:
DB_HOST=127.0.0.1
2. **Check Port Number**: XAMPP’s MySQL server typically runs on port 3306, but it’s worth confirming this. If it uses a different port, add it to `DB_PORT` in your `.env`:
DB_PORT=3306
3. **Verify Database Credentials**: Ensure `DB_DATABASE`, `DB_USERNAME`, and `DB_PASSWORD` in `.env` match the MySQL credentials in XAMPP. By default, XAMPP uses `root` with an empty password.
DB_DATABASE=your_database_name
DB_USERNAME=root
DB_PASSWORD=
4. **Restart Services**: Restart the Apache and MySQL services in XAMPP after making changes to `.env`.
5. **Clear Laravel Config Cache**: Run this command to clear any cached configuration:
php artisan config:cache
After making these adjustments, try accessing your Laravel application again. Let me know if the error persists!
