Javascript 从JSON对象获取字符串

我有一个名为$graphData的JSON对象，当我使用

时，我得到以下信息：

object(stdClass)[987]
  public 'myself' => 
    object(stdClass)[984]
      public '1' => 
        object(stdClass)[986]
          public 'id' => string '999999999' (length=9)
          public 'value' => string '4.2' (length=3)
          public 'name' => string 'Myself' (length=6)
          public 'owner' => string '' (length=0)
          public 'type' => int 1
          public 'children' => 
            array (size=0)
              ...
  public 'my_teams' => 
    array (size=0)
      empty
  public 'my_units' => 
    array (size=0)
      empty
  public 'companies' => 
    array (size=1)
      0 => 
        object(stdClass)[982]
          public 'id' => string '66' (length=2)
          public 'name' => string 'Company' (length=8)
          public 'owner' => string 'Name Name' (length=13)
          public 'value' => string '4.2' (length=3)
          public 'type' => string '4' (length=1)
          public 'children' => 
            array (size=0)
              ...

如何访问标记为“value”且值为4.2的字符串

谢谢

//编辑：我需要在php中使用它，或者在php中使用js代码：

$data = json_decode($graphData);
$value = $data->companies[0]->value;
//Or for the one stored under "myself"
$value = $data->myself->{'1'}->value;

在JavaScript中：

var value = data.companies[0].value;
//Or for the one stored under "myself"
value = data.myself[1].value;

你试过什么吗？在这两种语言中，这都是一项微不足道的任务。你有没有尝试过在“公司”中迭代？是的，我正在“我自己”下寻找一个。谢谢
