在 Laravel 中檢索數據格式

Question

我熟悉 CI 和 CakePHP，但在 Laravel 中是新手。 在互聯網上閱讀了 laravel 之后，我安裝了 laravel 並從數據庫中檢索數據，但我不明白檢索到的對象，這是什么？

App\Models\Question Object
(
    [primaryKey:protected] => id
    [fillable:protected] => Array
        (
            [0] => name
            [1] => email
            [2] => password
        )

    [hidden:protected] => Array
        (
            [0] => password
            [1] => remember_token
        )

    [connection:protected] => 
    [table:protected] => 
    [perPage:protected] => 15
    [incrementing] => 1
    [timestamps] => 1
    [attributes:protected] => Array
        (
            [id] => 1
            [t_num] => aP5z78e
            [university] => 5
            [course] => 1
            [branch] => 0
            [subject] => 6
            [type] => 1
            [year] => 2007,2011
            [session] => 
            [question] => State and explain Thevenin's therom with example.
            [paper_code] => 
            [marks] => 
            [slug] => state-and-explain-thevenins-therom-with-example
            [additional_info] => 
            [option_1] => 
            [option_2] => 
            [option_3] => 
            [option_4] => 
            [answer] => 
            [status] => 1
            [user_id] => 1
            [created] => 1439622767
            [modified] => 1439622767
        )

    [original:protected] => Array
        (
            [id] => 1
            [t_num] => aP5z78e
            [university] => 5
            [course] => 1
            [branch] => 0
            [subject] => 6
            [type] => 1
            [year] => 2007,2011
            [session] => 
            [question] => State and explain 
            [paper_code] => 
            [marks] => 
            [slug] => state-and-explain
            [additional_info] => 
            [option_1] => 
            [option_2] => 
            [option_3] => 
            [option_4] => 
            [answer] => 
            [status] => 1
            [user_id] => 1
            [created] => 1439622767
            [modified] => 1439622767
        )

    [relations:protected] => Array
        (
        )

    [visible:protected] => Array
        (
        )

    [appends:protected] => Array
        (
        )

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

    [dates:protected] => Array
        (
        )

    [dateFormat:protected] => 
    [casts:protected] => Array
        (
        )

    [touches:protected] => Array
        (
        )

    [observables:protected] => Array
        (
        )

    [with:protected] => Array
        (
        )

    [morphClass:protected] => 
    [exists] => 1
    [wasRecentlyCreated] => 
)

而在與其他模型的關系之后，它被絞死了。

Answer 1

它返回Eloquent 集合。 這是一個有很多有用的助手可用的對象。 您可以訪問對象的任何部分或在控制器、模型或視圖中迭代對象：

在控制器中：

$obj->id;

在一個觀點：

{{ $obj->name }}
