Scope

From the RFC

PHP has no object that represents a request. Most request state is stored in process-wide globals, or thread-local globals under ZTS. The request is simply the period between startup and shutdown. That works when a process handles one request at a time. It does not work as well when one process handles many requests, especially when they overlap. This RFC adds Scope: an object that identifies a unit of work, such as an HTTP request, queue job, or CLI command. Code can create a scope, run code in it, and get the current scope.
