Error report:

Declaration of ..... should be compatible with .....

Please use the following method to solve it

class  Model {
    /**设置分表名
     * @param  int $tableNum UID或表序号
     * @param int $num   位数
     * @return $this
     */
    public function tableSplit($tableNum=0,$num=2){
        $this->table($this->getTableNameSplit($tableNum,$num));
        return $this;
    }
}


class StockFlowModel extends Model {
    /**设置分表名
     * @param  int $tableNum UID或表序号
     * @param int $num
     * @return $this
     */
    public function tableSplit($tableNum=0,$num=4) {
        if(empty($tableNum)){
            $tableNum=date_time_format(DATE_TIME, 'ym');
        }
        parent::tableSplit($tableNum, $num);
        return $this;
    }
}

When calling the parent class method, use the parent:: method to call
