When to use trigger_error() vs throw new Error()?










3














I throw new Exception when I can catch a failure and do something about it. If I can't do something about it then I just trigger_error().



Now there's something new to me in PHP 7: throw new Error.



E.g.,



if (!mail(...))
throw new Error('...');


or



if (!mail(...))
trigger_error('...');


If I don't want to catch the error or do something in case mail() fails should I use throw new Error() or just the plain old trigger_error()?



What instances should we use throw new Error() vs a simple trigger_error()?

          The Error class was, as you already mentioned, introduced in PHP 7.



          It acts exactly like an exception since it implements Throwable.



          It's also subclasses by the following:



           ArithmeticError
          DivisionByZeroError
          AssertionError
          ParseError
          TypeError
          ArgumentCountError


          However, it does not behave like trigger_error(), in fact it behaves exactly like an exception(mostly because it is one).



          If you trigger_error() you can't catch it, because it's not an exception. Although there are workarounds.




          This is mostly guestimating on my part.



          I assume this exists for a more clear separation of Errors and Exceptions, possibly future plans include deprecating trigger_error and leaving just Error.




          To answer your question.



          I'd stick to throwing stuff rather than trigger_error. It's catchable, it's OOP.
