我有以下我从一个更大的数组中切下来的。现在我想循环遍历这个数组并过滤一些值。我已经使用带有 true 选项的 sliced_array 功能来保留 [2] 数组编号。

现在这个数组有几个子数组，我需要一些值和一些过滤。在最终结果中，我想创建一个列出数组编号（1 到 12）的表，并在其后面有链接。（所以是一个 2 列表）我不需要的是剧集编号中的第二个数组。这始终是情节中的 [1] 数组。这是“俄罗斯”部分，我的最终结果不需要它。

我怎样才能循环这个并得到一个简单的 html 表作为输出？我一直在尝试使用 foreach() 方法，但现在我得到的只是“数组”。

编辑答案确实是做多个foreach。

<?php
    $json = file_get_contents("http://trendico.ru/api/moviebox/get_tv_data?id=1&season=7");
    $array = json_decode($json, TRUE);


//Create an index array
$indexarray = (array_values($array));

//Create an array with only the episodes 
$episodes = array_slice($indexarray, 2, 1);



foreach($array as $arrayl1) {
    foreach($arrayl1 as $arrayl2) {
        foreach($arrayl2 as $arrayl3) {
            foreach($arrayl3 as $key => $val) {
                echo "$key=>$val"."<br>";
            }
        }
    }
}

?>

使用递归函数和is_array.

function doSomething(&$complex_array){
foreach ($complex_array as $n => $v)
{
    if (is_array($v))
        doSomething($v);
    else
        do whatever you want to do with a single node
}}

您可能不够深入，这应该可以：

foreach($array[2] as $link){
      if($choice == 'eng'){
          // the English
          echo $link[0]['id'] . " - ". $link[0]['link'];
      }
      elseif($choice == 'ru'){
          // the Russian
          echo $link[1]['id'] . " - ". $link[1]['link'];
      }
}

$array 是用于存储多维数组的变量，第一个元素是键为 2 的数组。我不知道为什么！？但仍然循环通过数组内部的数组。

您可以在所有数组中循环，直到获得所需的数据，因为数据位于第 4 级，所以让我们循环 4 次

foreach($array as $arrayl1) {
    foreach($arrayl1 as $arrayl2) {
        foreach($arrayl2 as $arrayl3) {
            foreach($arrayl3 as $key => $val) {
                echo "$key=>$val"."<br>";
            }
        }
    }
}

这将输出

id=>24339
active=>1
lang=>en
link=>http://vk.com/video_ext.php?oid=203859683&id=165118953&hash=545584bd3253fab9&hd=1
id=>24483
active=>1
lang=>ru // and so on

<?php
foreach($array as $smaller){
  foreach($smaller as $link){
     echo $link[0]['id'] . " > ". $link[0]['link']
