json解析php的问题

Question

我目前正在尝试使用 http://getpocket.com/developer/docs/v3/retrieve 路由将我的 php 应用程序绑定到 Pocket 应用程序 api。连接本身很好，我可以获得返回的 json。返回的json如下：

但是问题是我似乎无法有效地解析这个。整个数组似乎没有入口点（“列表”失败）。我认为每个数字条目也给我带来了问题。本质上，我试图遍历然后项目以提取相关数据，即每个条目的“given_title”，但无论哪种解析方法，我似乎都无法得到结果。

我目前在php中使用这种格式（明显错误）：

<?php
foreach ($result['list'] as $item){
 echo "Item: ", $item['item_id'];
}
var_dump(json_decode($result,true));
?>

任何帮助将不胜感激。

非常感谢。

Answer 1

您首先需要将json数据转换为数组。

“true”参数确保它返回一个关联数组而不是一个对象。 pre标签用于格式化。

$result = json_decode($json, true);
echo "<pre>";
foreach ($result["list"] as $value) {
    print_r($value);
}
echo "</pre>";

Answer 2

拳头，需要将json数据转为数组：

$result=json_decode($result);

foreach ($result['list'] as $item){
 echo "Item: ", $item['item_id'];
}
