1、生成控制器
php artisan make:controller PhotoController
2、使用RESTFUL生成控制器
php artisan make:controller PhotoController --resource
Route::resource('photo', 'PhotoController');
为什么用resource参数,因为我们在做一个后台的时候,设计到增删改查操作,而这些操作我们通过--resource就可以直接生成这些方法,Route::resource其实就是生成了快捷的路由,让我们本来需要写的Get,post,delete直接用restful方式一键生成了。需要注意的是index是列表,store是新增,show是详情,update是修改,,destory是删除。
3、生成模型
php artisan make:model User -m
生成user模型同时生成数据库创建文件
4、PHP数据表维护(迁移)
新建迁移:
php artisan make:migration create_users_table
新的迁移位于database/migrations目录下,每个迁移文件名都包含时间戳从而允许 Laravel 判断其顺序。
--table和--create选项可以用于指定表名以及该迁移是否要创建一个新的数据表。这些选项只需要简单放在上述迁移命令后面并指定表名:
php artisan make:migration add_votes_to_users_table --table=usersphp artisan make:migration create_users_table --create=users
运行迁移:
php artisan migrate
5、填充数据
新建填充:
php artisan make:seeder UserTableSeeder
运行填充器:
php artisan db:seed
php artisan db:seed --class=UserTableSeeder
你还可以使用migrate:refresh命令来填充数据库,该命令还可以回滚并重新运行迁移,这在需要完全重建数据库时很有用:
php artisan migrate:refresh --seed

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
