Description
Applications running on PHP 8.3 can access simple file-backed database formats through a common API. This runtime extension is used by scripts, caches, indexes, and compatibility layers that store key-value data outside a full database server. It is dependency-only and has no separate launcher; PHP code uses it when enabled. File permissions, locking, backups, and trusted paths matter because local database files can contain private records and can be damaged by concurrent writes.
