我正在使用 Illuminate 访问我的数据库

<body> 
 <?php
    $edges = Edge::all();

    foreach ($edges as $key => $value) {
    print $value;
    }
 ?>
</body>

浏览器返回：

{"childID":"A","parentID":"C","updated_at":null,"created_at":null}{"childID":"B","parentID":"E","updated_at":null,"created_at":null}{"childID":"C","parentID":"D","updated_at":null,"created_at":null}{"childID":"C","parentID":"F","updated_at":null,"created_at":null}{"childID":"Y","parentID":"Z","updated_at":"2014-08-07 10:26:54","created_at":"2014-08-07 10:26:54"}

至少对我来说奇怪或出乎意料的是我的结果以 JSON 格式返回。如果您能对此有所了解，即为什么会这样，或者原因是......我将不胜感激。

如果我将结果转储到浏览器中：

<?php
 print '<pre>';print_r($edges);
?>

产生：

 [items:protected] => Array
    (
        [0] => Edge Object

                [with:protected] => Array
                    (

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

        [1] => Edge Object
            (...)

 ...
)

就前端结果而言 - 我真的只对以下内容感兴趣：

[childID] => A
[parentID] => C
[updated_at] => 
[created_at] =>

物体的一部分；仅不在 JSON 中；纯文本。
