8. How do database migrations work in Laravel?
Answer:
Migrations work as version control for the database. Migration makes it easy to modify the database schema.
The Artisan command for creating migration schema is php artisan make:migration create_employeess_table. New migrations are stored in a database/migrations directory and each migration contains the name and timestamp so that Laravel can order migrations.
Table and create options can be used to indicate the name of the table and if the migration is used to create a new table. They pre-fill the migration stub file with the specified table:
php artisan make:migration create_employees_table --create=employees
php artisan make:migration add_departments_to_employee_table --table=employees
9. Explain how skip() and take() are used in Laravel Query.
Answer:
Skip() and take() limit the number of results in a query.
Skip() is used to skip over several results before continuing with the query. So if you want five results instead of ten, you’ll use skip(5).
And take() is used to specify how many results you want from the query.
10. Explain how dd() is used in Laravel.
Answer:
The helper function dd(), which stands for dump and die, is used to dump a variable’s contents to the browser and stop the further script execution.
11. Explain how the Eloquent cursor() method is used in Laravel.
Answer:
The cursor method is used to iterate through the database with a cursor that only executes a single query. This method aims to reduce memory usage while processing large amounts of data.
