### Solution 1: Add a `restart` policy for `phpmyadmin`
Adding a restart policy to `phpmyadmin` can ensure it tries to connect again if the database isn't ready yet.

phpmyadmin:
  image: phpmyadmin/phpmyadmin:latest
  container_name: phpmyadmin
  restart: always  # Add this line
  environment:
    PMA_HOST: db
    PMA_USER: laravel
    PMA_PASSWORD: password
    PMA_PORT: 3306
  ports:
    - "8082:80"
  depends_on:
    - db

### Solution 2: Use `depends_on` with `condition`
In Docker Compose v3.7 and above, you can add specific wait conditions to ensure that services start only when their dependencies are ready. You could look into using a third-party wait-for-it script, but `restart: always` often resolves the issue in most cases.

### Solution 3: Verify Network and Volume Configuration
Ensure your services are properly networked and the `db_data` volume is mounted correctly:

networks:
  laravel_network:
    driver: bridge

volumes:
  db_data:

### Solution 4: Check Docker Compose Version
Verify that you're using Docker Compose v3.8 or higher, as certain features may behave differently across versions.

### Solution 5: Restart Docker Compose
Sometimes, simply stopping and removing all services, followed by a fresh restart, can help Docker reconfigure the network.

docker-compose down -v
docker-compose up -d

Give these steps a try and let me know if it resolves the issue!
