Laravel's replicate() method allows developers to efficiently duplicate an existing Eloquent model instance, excluding primary key and timestamps.The replicate() method creates a shallow clone of a model instance, copying all attributes except primary key, created_at, and updated_at.Common use cases for replicate() include cloning product listings, duplicating form templates, and bulk-creating records based on a base model.Advanced usage of replicate() includes selective attribute replication and manually handling relationships for related models.
