QUESTION
I need some function that will accept a function as the parameter and will run it in try {} catch (Exception $e) {}. If it runs successfully, do nothing, otherwise, throw new Exception. That's something like function-checker, which checks functions if they ran successfully. Anybody can help me or give advice? Thanks for any replies.
The function should work like that:

Answered 2019-Jul-28 at 17:08Not every function throws an exception when they fail. Many functions, especially ones that have been around for a long time, simply trigger PHP errors rather than exceptions.
To handle those, you would use a custom error handler: https://www.php.net/manual/en/function.set-error-handler.php
So you could set up a custom error handler that would intercept those kinds of failures and throw them as exceptions. The whole point of that function is to do what you're trying to do - handle errors in a custom way.
