This project is a PHP environment manager and testing utility designed to back up and revert the global application state. It functions as a snapshotter that captures the current state of global variables and settings to prevent side effects between different execution contexts.
The tool focuses on automating testing environment control and ensuring test isolation within PHPUnit suites. It accomplishes this by snapshotting and reverting global state changes during execution to create predictable and reproducible conditions for software tests.
The system implements a backup-and-restore cycle that monitors changes to superglobals and server settings. This allows the environment to be returned to a known previous configuration through a restore-point mechanism.
