introduce the file b.php into the file a.php and execute a function c in b.php in a.php. At this point c throws an exception that cannot be caught in a. Environment: nginx,php-fpm.
nginx Direct 502

I'll give you some advice from your question:

  1. look at nginx's error log. Nginx can generally give you a good feedback.
  2. if you look at the error log of php-fpm, you can basically locate the error of PHP.
  3. generally speaking, there is something wrong with your program. I suggest you use catch (Error $e) to catch errors at the same time. If you report an error, you can't catch it without Error. Exception can only catch exceptions.

keep the above three points in mind.
