将JSON映射到php对象

我有一个JSON，它具有以下结构，但我只对entries节点中的数据感兴趣，因此我的DTO类的字段镜像所述节点内的标记。但正如期望的那样，当反序列化JSON时，我得到一个错误，因为JMSserializer期望一个包含JSON中所有标记字段的对象。有没有办法可以忽略其他标签？什么是完成这个的正确方法？将JSON映射到php对象

你试过'json_decode'？ – Burki

@Burki我想将它映射到一个对象，这就是为什么使用JMSserializer。 – user3163473

你可能还会'json_decode'，然后提取你需要的部分，如果你不能提出一个更好的想法，'json_encode'是相关的部分。 – Burki

使用json_decode()为：

$arr = json_decode($json_string, true); 
$entries = $arr['result']['data']['pages']['entries']; 
print_r($entries);

输出：
