Article Introduction：There are three main ways to create custom verification rules in Laravel, suitable for different scenarios. 1. Use Rule class to create reusable verification logic: generate a class through phpartisanmake:ruleValidPhoneNumber, and introduce and use it in the controller, suitable for complex and reusable situations; 2. Use closures in verification rules: directly write one-time verification logic in the validate method, such as checking the length of the username, suitable for simple and only once-using scenarios; 3. Add custom rules in FormRequest: add closures or introduce Rule classes in the rules() method of form requests, which are clear and easy to manage; in addition, you can also use att

Article Introduction：spl_autoload_register() is a core function used in PHP to implement automatic class loading. It allows developers to define one or more callback functions. When a program tries to use undefined classes, PHP will automatically call these functions to load the corresponding class file. Its main function is to avoid manually introducing class files and improve code organization and maintainability. Use method is to define a function that receives the class name as a parameter, and register the function through spl_autoload_register(), such as functionmyAutoloader($class){require_once'classes/'.$class.'.php';}spl_

Article Introduction：For account security, when you log in to WeChat on a new device for the first time, you need to enter your WeChat account and password, or your mobile phone number and verification code. Then, you will be prompted to complete the secondary verification. The optional method is as follows: use the old logged in device to open WeChat and scan the QR code on the screen to complete verification. Log in again to verify through your account password, or mobile phone number and verification code. Use the bound email to receive the verification code and enter it to complete the login. Invite friends to assist in verification. Invite two common contacts to send verification codes to your account, and then refresh the page to view verification results. After completing any of the above verification methods, you can successfully log in to your account.

Article Introduction：PHP Custom Annotations: Enhanced Code Flexibility and Scalability This article discusses how to create and use custom annotations in Symfony 3 applications. Annotations are the document block metadata/configuration we see above classes, methods and properties. They are often used to declare controller routing (@Route()), Doctrine ORM mapping (@ORM()), or control Rauth and other packages. Types and methods of access. This article will explain how to customize annotations and read class or method information without loading the class. Key points: PHP custom annotations can be used to add metadata to your code, affecting your code behavior, making it more flexible and easier to adapt. They can be used to define routing information, specify verification rules, or configure dependency injection.

Article Introduction：To write clean and easy-to-maintain JavaScript code, you need to follow naming specifications, split functions, reasonable annotations, and use modern syntax. 1. Use consistent naming specifications, such as getUserData(), isLoading, UserProfile, and use ESLint or Prettier to unify the style; 2. Split the giant functions into small modules, such as splitting the form submission into verification, formatting, and sending requests; 3. Add necessary comments to explain the logical reasons, and annotate the public API with JSDoc; 4. Use ES6 features such as const/let, arrow functions, and deconstruction assignment to improve readability.

Article Introduction：To create your own C# custom properties, you first need to define a class inherited from System.Attribute, then add the constructor and attributes, specify the scope of application through AttributeUsage, and finally read and use them through reflection. For example, define the [CustomAuthor("John")] attribute to mark the code author, use the [CustomAuthor("Alice")] to modify the class or method when applying, and then obtain the attribute information at runtime through the Attribute.GetCustomAttribute method. Common uses include verification, serialization control, dependency injection, and

Article Introduction：The core methods of Python metaprogramming include: 1. Use type to dynamically create classes; 2. Control the class creation process through metaclasses; 3. Use decorators to modify functions or class behavior; 4. Dynamically modify object functions at runtime. These mechanisms allow developers to dynamically generate or modify code structures at runtime. For example, type can construct classes based on parameters, metaclasses can be used for interface consistency verification or automatically register subclasses, decorators are widely used in property encapsulation or framework routing management, while monkey patches support temporary enhancement class functionality, suitable for testing mocks or emergency fixes, but abuse should be avoided to maintain code maintainability.
