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.

Laravel Eloquent relationships tutorial
LaravelEloquentRelationships provides five main types: 1. One-to-one uses hasOne and belongsTo; 2. One-to-many uses hasMany and belongsTo; 3. Many-to-many uses belongsToMany and creates intermediate tables; 4. Indirect association uses hasManyThrough; 5. Polymorphic association uses morphTo and morphMany. Each relationship is achieved by defining methods in the model. Eloquent automatically processes underlying queries, making data access more intuitive and efficient.

How to update Laravel to the latest version?
Upgrading Laravel to the latest version requires caution. 1. Check the difference between the current version and the target version, confirm the upgrade path and read the BreakingChanges in the official document; 2. Be sure to back up the code and database before upgrading, so that it can quickly roll back if errors occur; 3. Modify the Laravel version number in composer.json and check whether other dependencies are compatible; 4. Run composerupdate and deal with possible PHP version, extension or package conflict problems; 5. Clean up the Laravel cache and regenerate the optimization file to ensure that the new functions are running normally; 6. Test core functions such as login, database reading and writing, queue tasks, API interface and third-party service docking, and verify them by module.
