解析具有多个嵌套的PHP数组

Question

我是一个新手，正在寻找解析PHP数组的帮助。我已经生成了以下数组，它保存在：

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

如您所见，每个项目的状态属性为0或1.我正在寻找一种简单的方法来遍历每个项目，并找出有多少状态为0，有多少状态为1。 / p>

我试过使用一个简单的foreach但没有成功。问题是，没有返回任何内容，所以我认为我没有正确解析数组。

如果我做一个简单的print_r，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;

}

任何帮助非常感谢！

Answer 1

我想你想迭代 list 数组吗？

$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;
