  The database resource, returned by dbase_open() or dbase_create().

### 返回值

成功时返回 `true`， 或者在失败时返回 `false`。

### 更新日志

PECL dbase 7.0.0 | `database` is now a resource instead of an int.

if ($db) {
$record_numbers = dbase_numrecords($db);
for ($i = 1; $i <= $record_numbers; $i++) {
dbase_delete_record($db, $i);
}
