In this chapter, you received an overview of major changes in error handling in PHP 8. You were also given examples of situations where error conditions might arise, and now have an idea of how to properly manage errors in PHP 8. You now have a solid path toward refactoring code that under PHP 8 now produces errors.

In a like manner, although the second set of error conditions described only produced Notices in the past, these same conditions now cause a Warning. The new set of Warnings gives you a chance to adjust faulty code and prevent having your application devolve into a seriously unstable condition.
Finally, you learned how use of the @ operator is strongly discouraged. In PHP 8, this syntax will no longer mask fatal errors. In the next chapter, you will learn how to create C-language structures and make direct calls to...
