The above error-reporting article describes these two reporting levels:

// Report all PHP errors (see changelog)
error_reporting(E_ALL);

// Report all PHP errors
error_reporting(-1);

What is the difference between the two? When would you use one instead of the other?

Please update the article with a clear explanation of the differences and an example of the correct use cases for each level.
