getDbFields() public method

获取表字段-因为mongodb中collection对字段是没有做强制一制的。这边默认获取第一条数据的所有字段返回

public getDbFields ( string $table, mixed $tablePrefix = null, integer $filter ) : mixed
$table	string	表名
$tablePrefix	mixed	表前缀为null时代表table已经带了前缀
$filter	integer	在MongoDB中此选项无效
return	mixed

    public function getDbFields($table, $tablePrefix = null, $filter = 0)
    {
        is_null($tablePrefix) && ($tablePrefix = $this->tablePrefix);
        $one = $this->runMongoQuery($tablePrefix . $table, [], ['limit' => 1]);
        return empty($one) ? [] : array_keys($one[0]);
    }
