解析一个带有多个嵌套的PHP数组

Question

我是一个新手，正在寻找一些解析PHP数组的帮助。我已经生成以下数组并将其保存在：

$items = $pocket->retrieve($params, $accessToken); 

正如你所看到的，每个项目都有一个状态属性，是0或1。我的每个项目，寻找一种简单的方法来循环并找出多少有状态0和多少有状态1.

我试过使用一个简单的foreach但没有成功。问题是，没有返回，所以我不认为我正确解析数组。

如果我做了一个简单的print_r打印出数组。

print_r($items); 

我有什么至今：

$items = $pocket->retrieve($params, $accessToken); 
$hasRead = 0; 
$hasNotRead = 0; 

foreach ($items as $key) { 

    if ($key["status"] == 1) { 
     $hasRead++; 
    } 
    else { 
     $hasNotRead++; 
    } 

    echo "Read = " . $hasRead; 
    echo "Not Rad = " . $hasNotRead; 

} 

任何帮助，非常感谢！

Answer 1

我认为要正确遍历列表阵列？

$items = $pocket->retrieve($params, $accessToken); 
$hasRead = 0; 
$hasNotRead = 0; 

foreach ($items['list'] as $key) { //Added list 

    if ($key["status"] == 1) { 
     $hasRead++; 
    } 
    else { 
     $hasNotRead++; 
    } 

} 

echo "Read = " . $hasRead; 
echo "Not Rad = " . $hasNotRead;
