Examining the FFI Class

Not every developer has a need to use the FFI extension. Having direct experience with the FFI extension deepens our understanding of the internals of the PHP language, and this deepened understanding can have a beneficial impact on the career of a PHP developer: it’s quite possible that at some point in the future, you will be employed by a company that has developed a custom PHP extension. Knowing how to operate the FFI extension in this situation allows you to develop new features for a custom PHP extension, as well as to help you troubleshoot extension problems.
