1 模型

    const GENDER_UN = 10;//未知
    const GENDER_BOY = 20;//男
    CONST GENDER_GRIL= 30;//女

    public function gender($ind = null)
    {
        $arr = [
            self::GENDER_UN=>'未知',
            self::GENDER_BOY=>'男',
            self::GENDER_GRIL=>'女'
        ];
        if ($ind !== null){
            return array_key_exists($ind,$arr) ? $arr[$ind] : $arr[self::GENDER_UN];
        }
        return $arr;
    }

/*        foreach ($students as $student){
            dd($student->gender());
