Delete records: call delete() or deleteAll(). Pay attention to verification, secure assignment and soft deletion policies to ensure correct and secure operation.

How to use updateOrCreate in Eloquent?
updateOrCreate is used in Laravel to update or create records according to the search conditions. It first looks for matching records. If there is, the specified field will be updated.

How to customize the key for route model binding to use a slug?
In Laravel, using slug instead of id for routing model binding can be achieved by overriding the getRouteKeyName method. First, rewrite the getRouteKeyName method in the model to return 'slug'; second, it is recommended to add a unique index to the slug field to ensure accuracy and check the uniqueness of the existing data; finally, keep the route and controller code unchanged, Laravel will automatically parse the model through slug. In addition, pay attention to issues such as clearing routing cache, handling soft deletion situations, and field naming consistency.

How to perform a raw SQL query in Laravel?
There are three main ways to run raw SQL queries in Laravel. First, use the DB::select method to execute the original query, pass the SQL string and bind parameter array to prevent SQL injection and return the resulting object array; second, use DB::statement() to perform insert, update or delete operations; finally, use DB::raw() to embed raw SQL fragments in Eloquent queries, which are suitable for complex queries or aggregation logic, but excessive use should be avoided to maintain maintainability. Always use parameter binding to ensure security and use raw SQL only when necessary (such as complex queries, performance optimization, or legacy databases) to reduce dependency on specific database engines.

How to use the tap helper function in Laravel?
tap() returns the original value, allowing side-effect operations to be performed without interrupting chain calls; 1. Used to save the model and return instances, such as tap(newUser([...]))->save(); 2. Modify the object while maintaining chain calls, such as tap($user)->update(['active'=>false]); 3. Record intermediate values during debugging, such as tap(...)->toArray(); it always returns the original value rather than the callback result, is suitable for objects, arrays or basic types, and is ideal for processing logs, events or saving operations.
