Method to implement automatic dependency injection based on reflection mechanism in PHP
This article mainly introduces the method of automatic dependency injection in PHP based on the reflection mechanism. It analyzes the steps, principles and related operating techniques of using reflection to realize automatic dependency injection in PHP in the form of examples. Friends in need can refer to it
The example in this article describes how PHP implements automatic dependency injection based on the reflection mechanism. I share it with you for your reference. The details are as follows:
Dependency injection is also called inversion of control. Anyone who has used the framework should be familiar with it. Many people think it is something very high-end when they see the name, and are daunted by it. Today I took the time to do some research and unravel its mystery. Without further ado, let’s go straight to the code;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 |

The above code uses PHP’s reflection function to create a container class and use this class to implement other classes Dependency injection function. The above dependency injection is divided into two types, one is dependency injection of constructor, and the other is dependency injection of method. We use the following three classes for testing.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 |

Test dependency injection of constructor
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
|
Test method dependency injection

It can be seen from the above two examples that when we create an object or call a method, we don’t need to know the The class or this method depends on that class. Using the reflection mechanism can easily automatically inject the required classes for us.

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,
