                    [visible:protected] => Array

                    [guarded:protected] => Array
                        (
                            [0] => *
                        )

                )

        )

)

但是我只想得到'attributes:protected'在laravel中形成整个数组.我已经尝试过

But i want to get only 'attributes:protected' Form whole array in laravel . I have already tried

echo $ data = $ this-> getAttributes()['firstname']; 但这会返回错误

Undefined index: firstname

请帮助我解决问题

在此先感谢您的帮助和时间.

推荐答案

一种非常简单的方法:

$arr = $this->all()->toArray();

var_dump($arr); // oh~ array data!
