Description
Scripts running on PHP 8.3 can inspect Unix users, groups, permissions, process IDs, and terminal details. This runtime extension adds POSIX functions used by command-line tools, service helpers, and installers that need system identity information. It is dependency-only and has no separate launcher; PHP code calls it when enabled. Returned system details can influence permission checks or expose account metadata, so scripts should avoid leaking results to untrusted users.
