Regarding the issue of callback verification on the public platform

Question

Since the verification always failed, I deleted all the code in the program and kept only three sentences to check whether the program was executed.

The first sentence, file_put_contents('x.txt','1'); writes 1 to x.txt, indicating that the program is executed and the first sentence is normal.

The second sentence, include_once "pkcs7Encoder.php"; load the interface file

The third sentence, file_put_contents('x.txt','2'); Write to x.txt Enter 2 to indicate that the second sentence is executed normally.

It turned out that the program terminated after executing the second sentence. Originally, the interface provided by Tencent has 5 files. I have tried them all. As long as this file is included, the program will terminate execution.

What is the reason for this?

Answer 1

You can check if there are any breakpoints in the code in the file you imported.

Answer 2

There is a problem importing the file
