dba_sync

(PHP 4, PHP 5, PHP 7, PHP 8)

dba_sync — Synchronize database

dba_sync(Dba\Connection $dba): bool

dba_sync() synchronizes the database. This will probably trigger a physical write to the disk, if supported.

dba: A Dba\Connection instance, returned by dba_open() or dba_popen().

成功时返回 true，或者在失败时返回 false。

版本	说明
8.4.0	The `dba` parameter expects a Dba\Connection instance now; previously, a valid `dba` resource was expected.
