What are the valid use cases of goto in PHP?

I know, there are other questions about the goto statement introduced in PHP 5.3.

But I couldn't find any decent answer in there, all were of the type "last resort", "xkcd", "evil", "bad", "EVIL!!!". But no valid example. Only statements that there aren't any uses. Or statements that there are some rare use cases (again, without examples).

So, the question is: "What are the valid use cases of goto in PHP?". Answers for "Is goto evil?" are not welcome and will get downvoted. Thanks :)

Or does somebody have a link to an RFC where the decision is explained - I couldn't find one.

Solution

  • One possible use (that can however be be implemented using other means) is implementation of a finite state machine.
