Another big area that could cause trouble, are features that have been removed. This should really only be an issue if you’re working with an older code base, because the features that have been removed are primarily ones that have been deprecated for a long time. If you’ve been putting off making these necessary changes, the huge advantage in speed with PHP7 should help convince you, or management, to take the time needed to update your code. I’ve included information and tools in the Teacher’s Notes that can help make it much less painful.
