Display all files and folders PHP file and folder operations (create, delete, move, copy)
Create the FileUtil.php file, the content and calling method are as follows:
<?<span>php
</span><span>/*</span><span>*
* 操纵文件类
*
* 例子：
* FileUtil::createDir('a/1/2/3'); 测试建立文件夹 建一个a/1/2/3文件夹
* FileUtil::createFile('b/1/2/3'); 测试建立文件 在b/1/2/文件夹下面建一个3文件
* FileUtil::createFile('b/1/2/3.exe'); 测试建立文件 在b/1/2/文件夹下面建一个3.exe文件
* FileUtil::copyDir('b','d/e'); 测试复制文件夹 建立一个d/e文件夹，把b文件夹下的内容复制进去
* FileUtil::copyFile('b/1/2/3.exe','b/b/3.exe'); 测试复制文件 建立一个b/b文件夹，并把b/1/2文件夹中的3.exe文件复制进去
* FileUtil::moveDir('a/','b/c'); 测试移动文件夹 建立一个b/c文件夹,并把a文件夹下的内容移动进去，并删除a文件夹
* FileUtil::moveFile('b/1/2/3.exe','b/d/3.exe'); 测试移动文件 建立一个b/d文件夹，并把b/1/2中的3.exe移动进去
* FileUtil::unlinkFile('b/d/3.exe'); 测试删除文件 删除b/d/3.exe文件
* FileUtil::unlinkDir('d'); 测试删除文件夹 删除d文件夹

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
