解析一個帶有多個嵌套的PHP數組

Question

我是一個新手，正在尋找一些解析PHP數組的幫助。我已經生成以下數組並將其保存在：

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

正如你所看到的，每個項目都有一個狀態屬性，是0或1。我的每個項目，尋找一種簡單的方法來循環並找出多少有狀態0和多少有狀態1.

我試過使用一個簡單的foreach但沒有成功。問題是，沒有返回，所以我不認爲我正確解析數組。

如果我做了一個簡單的print_r打印出數組。

print_r($items); 

我有什麼至今：

$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; 

} 

任何幫助，非常感謝！

我認爲要正確遍歷列表陣列？

$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;
