What are the system requirements for running Laravel?

The most common way to generate a named route in Laravel is to use the route() helper function, which automatically matches the path based on the route name and handles parameter binding. 1. Pass the route name and parameters in the controller or view, such as route('user.profile',['id'=>1]); 2. When multiple parameters, you only need to pass the array, and the order does not affect the matching, such as route('user.post.show',['id'=>1,'postId'=>10]); 3. Links can be directly embedded in the Blade template, such as viewing information; 4. When optional parameters are not provided, they are not displayed, such as route('user.post',

Laravel's configuration cache improves performance by merging all configuration files into a single cache file. Enabling configuration cache in a production environment can reduce I/O operations and file parsing on each request, thereby speeding up configuration loading; 1. It should be enabled when the application is deployed, the configuration is stable and no frequent changes are required; 2. After enabling, modify the configuration, you need to re-run phpartisanconfig:cache to take effect; 3. Avoid using dynamic logic or closures that depend on runtime conditions in the configuration file; 4. When troubleshooting problems, you should first clear the cache, check the .env variables and re-cache.

The core of handling HTTP requests and responses in Laravel is to master the acquisition of request data, response return and file upload. 1. When receiving request data, you can inject the Request instance through type prompts and use input() or magic methods to obtain fields, and combine validate() or form request classes for verification; 2. Return response supports strings, views, JSON, responses with status codes and headers and redirect operations; 3. When processing file uploads, you need to use the file() method and store() to store files. Before uploading, you should verify the file type and size, and the storage path can be saved to the database.

There are two main methods for request verification in Laravel: controller verification and form request classes. 1. The validate() method in the controller is suitable for simple scenarios, directly passing in rules and automatically returning errors; 2. The FormRequest class is suitable for complex or reusable scenarios, creating classes through Artisan and defining rules in rules() to achieve code decoupling and reusing; 3. The error prompts can be customized through messages() to improve user experience; 4. Defining field alias through attributes() to make the error message more friendly; the two methods have their advantages and disadvantages, and the appropriate solution should be selected according to project needs.

The main difference between LaravelBreeze and Jetstream is positioning and functionality. 1. In terms of core positioning, Breeze is a lightweight certified scaffolding that is suitable for small projects or customized front-end needs; Jetstream provides a complete user system, including team management, personal information settings, API support and two-factor verification, which is suitable for medium and large applications. 2. In terms of front-end technology stack, Breeze uses Blade Tailwind by default, which prefers traditional server-side rendering; Jetstream supports Livewire or Inertia.js (combined with Vue/React), which is more suitable for modern SPA architectures. 3. In terms of installation and customization, Breeze is simpler and easier to use

Laravel's EloquentScopes is a tool that encapsulates common query logic, divided into local scope and global scope. 1. The local scope is defined with a method starting with scope and needs to be called explicitly, such as Post::published(); 2. The global scope is automatically applied to all queries, often used for soft deletion or multi-tenant systems, and the Scope interface needs to be implemented and registered in the model; 3. The scope can be equipped with parameters, such as filtering articles by year or month, and corresponding parameters are passed in when calling; 4. Pay attention to naming specifications, chain calls, temporary disabling and combination expansion when using to improve code clarity and reusability.

Database Factory is a tool in Laravel for generating model fake data. It quickly creates the data required for testing or development by defining field rules. For example, after using phpartisanmake:factory to generate factory files, sets the generation logic of fields such as name and email in the definition() method, and creates records through User::factory()->create(); 1. Supports batch generation of data, such as User::factory(10)->create(); 2. Use make() to generate uninvented data arrays; 3. Allows temporary overwriting of field values; 4. Supports association relationships, such as automatic creation
