我正在处理一个以下列格式返回信息的对象...我删除了一些细节，其中信息有点重复以节省一些空间。

我需要提取ID，名称等详细信息，以便分别显示4cff5974138c9，Mac Pro等。我怎么能这样做？

你需要调用该类的函数（其中ISC_QUOTE_ITEM是一个对象 - 比如MyClass），它返回受保护的变量

修改
它可以访问。我是对的。

喜欢这个 -

如果您还没有，请在班级MyClass内添加一个功能。

public function getName()
{
  return $this->name;
}

然后在你的代码中你可以这样做： - 

echo $obj->getName();

阅读http://php.net/manual/en/language.oop5.visibility.php，了解有关变量类型可见性的详细信息

您可以使用反射器构造来完成此操作：

取自http://www.php.net/manual/en/reflectionclass.getproperties.php：

的示例 
<?php
class Foo {
    public    $foo  = 1;
    protected $bar  = 2;
    private   $baz  = 3;
}

$foo = new Foo();

$reflect = new ReflectionClass($foo);
$props   = $reflect->getProperties(ReflectionProperty::IS_PUBLIC | ReflectionProperty::IS_PROTECTED);

foreach ($props as $prop) {
    print $prop->getName() . "\n";
}

var_dump($props);

?>

正如您所看到的，还会返回受保护的$bar :)并查看http://www.php.net/manual/en/reflectionproperty.getvalue.php#98643，其中显示了如何返回受保护属性的值。
