@access
Scope of use: class, function, var, define, module
This tag is used to indicate the access permission of keywords: private, public or protected
@author
Specify the author
@copyright
Scope of use: class, function, var, define, module, use
Indicate copyright information
@deprecated
Usage scope: class, function, var, define, module, content, global, include
Indicate unused or obsolete keywords
@example
This tag is used for parsing A section of file content and highlight them. Phpdoc will try to read the file content from the file path given by this tag
@const
Using scope: define
Used to specify the constant defined in php
@final
Using scope: class, function, var
Indicate that the keyword is a The final class, method, and attribute are prohibited from being derived or modified.
@filesource
Similar to example, except that this tag will directly read the content of the currently parsed php file and display it.
@global
Indicates the global variable referenced in this function
@ingore
Used to ignore specified keywords in the document
@license
Equivalent to in the html tag, first is the URL, and then is to be displayed The content
For example Baidu
can be written as @license http://www.baidu.com Baidu
@link
Similar to license
But you can also point to any keyword in the document through link
@name
Specify an alias for the keyword.
@package
Usage scope: page level -> define, function, include
Class level ->class, var, methods
Used to logically group one or several keywords into a group.
@abstrcut
Indicates that the current class is an abstract class
@param
Specifies the parameters of a function
@return
Specifies the return pointer of a method or function
@static
Specifies that the keyword is static.
@var
Indicate the variable type
@version
Indicate the version information
@todo
Indicate the areas that should be improved or not implemented
@throws
Indicate the error exceptions that this function may throw, and the extreme situations
As mentioned above, Ordinary document tags must be marked with @ at the beginning of each line. In addition, there is also a tag called inline tag, represented by {@}, which includes the following types:
{@link}
Usage is the same as @link
{@source}
Display the content of a function or method
The above introduces the http://www.hunanzhibo.com/ php annotation specifications, including the content of http://www.hunanzhibo.com/. I hope it will be helpful to friends who are interested in PHP tutorials.

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,

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

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.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
