Discovering What Has Been Removed from the Core

Examining functions removed in PHP 8

There are a number of functions in the PHP language that have only been retained thus far in order to maintain backward compatibility. However, maintenance of such functions drains resources away from core language development. Further, for the most part, such functions have been superseded by better programming constructs. Accordingly, there has been a slow process whereby such commands have been slowly dropped from the language as evidence has mounted that they are no longer being used.
