Description
Legacy PHP 8.0 command-line programs can control Unix processes for workers, daemons, and job runners. This runtime extension adds process forking, signal handling, waits, alarms, and related control features used outside normal web request handling. It is dependency-only and has no desktop launcher; PHP CLI scripts use it after the extension is enabled. Process control can stop jobs, spawn extra work, or interact with privileges, so it belongs on systems where administrators trust the PHP scripts that call it.
