Description
Legacy PHP 8.1 applications can use PDO connections to SQL Server or Sybase-compatible databases through DB-Library. This runtime extension supports older business apps, migration scripts, and reporting tools that need those database backends. It is dependency-only and has no separate launcher; PHP code uses it with PDO after server and credential settings are configured. Driver trust, credentials, query parameters, and backups should be reviewed because the module can reach sensitive production records.
