PHP Framework

Yii: The only feature that make it better than others

The unique feature of the Yii framework is its event-driven mechanism. 1) It is implemented through event and event processors, allowing hooking at any link of the application, enhancing flexibility and scalability. 2) Event driver improves the reusability and modularity of the code, and simplifies testing and debugging. 3) However, it is necessary to note that excessive use may increase complexity and careful design should be carried out to ensure the maintenance and predictability of the system.

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.

How to configure Nginx for a Laravel application?

To correctly configure Nginx to run Laravel applications, you must 1. Set documentroot to the public directory; 2. Use try_files to implement URL rewriting; 3. Configure PHP-FPM to process PHP files; 4. Disable access to sensitive files and directories. The specific steps are: First, set root to /var/www/laravel/public to ensure that the entry file is public/index.php, and avoid exposing sensitive files such as .env; then use try_files$uri$uri//index.php?$query_string in location/ to implement the front-end controller mode, please

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.

Using Form Requests for Validation in Laravel.

Use FormRequests to extract complex form verification logic from the controller, improving code maintainability and reusability. 1. Creation method: Generate the request class through the Artisan command make:request; 2. Definition rules: Set field verification logic in the rules() method; 3. Controller use: directly receive requests with this class as a parameter, and Laravel automatically verify; 4. Authorization judgment: Control user permissions through the authorize() method; 5. Dynamic adjustment rules: dynamically return different verification rules according to the request content.
