Algorithm-how does php generate a unique incremental number?

1. method 2 of using the MySQL auto-increment field is not accepted. in high concurrency, make sure that the unique increment is 3. using C language to compile PHP extensions does not count first. Thank you! 1. the method of using the MySQL auto-increment field is not accepted.
2. Ensure high concurrency Unique Increment
3. Using C language to write PHP extensions is not counted

Refer to the ObjectID algorithm of MongoDB. You can consider including the following parts in the ID to prevent conflicts.

• Machine hash (preventing ID conflicts between multiple machines)
• Process ID (preventing multi-process conflicts)
• Timestamp (SEC)
• Auto-increment value (auto-increment in the same second)

Putting the time at the most meeting can achieve a basically increasing effect
