How to configure php errors logging?

Question

PHP

Apache works in conjunction with php 5.4
Problem:
In case of a clear fatal error situation, Apache returns an empty page with code 200. PHP errors are not displayed and are not written to the log
The path to the log is configured in the Apache config, the file is there and it is empty. Access logs are written successfully
The display of all errors is configured in the PHP config and logging is enabled.
Tell me where to dig?

Answer 1

All fatal errors are displayed and logged, I can assure you of this. But if these are application logic errors, then in fact there is no error, Exception() or trigger_error() or its alias users_error() will help you
