The problem in case 4 is to implement a database restoration process from a selected backup file to the current database. The restoration process should handle cases where the structure of the backup database may differ from the current database. Specifically, it should:

Allow the user to select a backup file from a list of available backup files.

Verify whether database migrations have been executed. If not, execute them before proceeding with the restoration process.

Restore data from the selected backup file to corresponding tables in the current database.

Handle cases where tables or columns exist in the current database but not in the backup file. In such cases, either set the values of missing columns to default values or NULL, depending on their data types.

Ensure that only matching tables found in the backup file are restored to the current database.

Display appropriate messages to inform the user about the restoration process and any encountered issues.

Prompt the user to confirm whether they want to continue after the restoration process is complete.

The solution should be implemented in Bash scripting, leveraging MySQL commands for database operations, and PHP commands for Laravel-specific tasks such as checking migration status. The script should be robust, handling errors gracefully and providing meaningful feedback to the user throughout the process.
This is the link to the problem.. thanks
