error_reporting(E_ALL)与error_reporting(-1)[重复]

I have been using error_reporting(E_ALL) exclusively, and recently read online where someone insisted that error_reporting(-1) was "the only way to go." Can anyone think of a situation where -1 would be advisable, or necessary, over E_ALL?

Perhaps I've been missing the boat, but I don't see where E_ALL is not sufficient.

Any insight would be welcome. Thanks!
