This article mainly introduces PHP to generate unique RequestID class, which has certain reference value. Now I share it with everyone. Friends in need can refer to it

This article introduces PHP to generate unique The RequestID class uses the session_create_id() and uniqid() methods to ensure uniqueness, and provides complete code and demonstrations for everyone to learn and use.

Current system designs generally use distributed systems. A request may call several microservices for processing, and finally return the result. When there is a problem with a request, it is difficult for us to track which microservice has the problem.

When each request accesses the server, we can add a unique identifier (RequestID) to this access, at the beginning of the request, during the request process, and at the end of the request , write the key data of this request process into the log (such as the parameters during the access, the methods passed, the microservices, the data returned at the end, etc.), which can be used for reference when there is a problem with the access to facilitate tracking of the problem.


For example, a request needs to go through several microservices before returning the output

Request->A->B->C-A->Output

If there is no output during the access process, or there is an error in the output, we can find the logs corresponding to A, B, and C based on the RequestID to check which service has the problem.

The code is as follows:

RequestID.class.php

demo:

Output:

Notesession_create_idmethod requiresphp7.1 Only versions above can be used.

For the session_create_id method, please refer to the official website instructions:
