使用 codeigniter 4 进行数据库备份

Question

我想备份 CI 4 中的数据库。

$model = new class extends \CodeIgniter\Model {
        protected $table      = 'form';
        protected $primaryKey = 'id';
    };
    $db = \Closure::bind(function ($model) {
        return $model->db;
    }, null, $model)($model);
    
    $util = (new \CodeIgniter\Database\Database())->loadUtils($db);

现在我想以 SQL 格式保存表格。 提前致谢。

public function backup_db(){
$model = new class extends \CodeIgniter\Model {
protected $database      = 'options';
protected $primaryKey = 'option_id';
    };
    $db = \Closure::bind(function ($model) {
    return $model->db;
    }, null, $model)($model);

    $util = (new \CodeIgniter\Database\Database())->loadUtils($db);
    echo $util->getXMLFromResult($model->get());
}
