php - The browser executes the program once and is executed multiple times by the server

Question

My problem is similar to this http://bbs.csdn.net/topics/39...

WeChat template message, I only called the template message interface once, but the entire program was actually executed N times.
The code does not use loops, and after curl post, exit() is done at the end;
I don’t know why, the program was re-executed N times
