解析具有多个嵌套的PHP数组

我是一个新手，正在寻找解析PHP数组的帮助。我已生成以下数组，并将其保存在中：

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

如您所见，每个项目都有一个状态属性，该属性为0或1。我正在寻找一种简单的方法来循环浏览每一项，找出有多少项状态为0，有多少项状态为1

我曾尝试使用一个简单的foreach，但没有成功。问题是，没有返回任何内容，因此我认为我没有正确解析数组

如果我做一个简单的打印，它会打印出数组

print_r($items); 

到目前为止，我所拥有的：

$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;

}

非常感谢任何帮助

我想你想迭代列表数组，对吗

$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;

是的，foreach循环是正确的方法。看起来您没有尝试任何操作，否则您会显示代码（！）请参阅我的编辑以包含我编写的代码。我认为我的foreach不能正常工作。另一个简单的问题是——如果我想弄清楚——“每天有多少篇文章被阅读”——这是否同样简单？有一个$list[time_read]值，所以我可以解析它们吗？
