从数组数组获取值 [英] Getting values from array of arrays

问题描述

我有一个数组数组.我正在尝试遍历每个变量并获取值. 这是我用来进入数组的代码，

I have an array of arrays. I am trying to loops through each of it and get values. Here is the code I am using to go into the array,

        $body = json_decode($res->getBody(),true); //gets the whole json and make an array
        $events = $body['results']; // to go one level down and get 'results'
        //var_dump($events);

        foreach ($events as $obj) {
            var_dump($obj); // to go into the array of arrays and print each inside array.
           break;
        }

我需要循环的数组:

array(1) {
  ["events"]=>
  array(43) {
    [0]=>
    array(22) {
      ["item1"]=>
      string(71) "lorem ipsum bla bla"
      ["lorem ipsum bla bla"]=>
      string(21) "lorem ipsum bla bla"
      ["lorem ipsum bla bla"]=>
      string(17) "lorem ipsum bla bla"
      ["lorem ipsum bla bla"]=>
      string(10) "lorem ipsum bla bla"
 }
    [1]=>
    array(22) {
      ["item1"]=>
      string(71) "lorem ipsum bla bla"
      ["lorem ipsum bla bla"]=>
      string(21) "lorem ipsum bla bla"
      ["lorem ipsum bla bla"]=>
      string(17) "lorem ipsum bla bla"
      ["lorem ipsum bla bla"]=>
      string(10) "lorem ipsum bla bla"
}

当我遍历单个项目时数组显示的内容:

它向我展示了完整的阵列

What the array shows when I loop over a single item:

It shows me the complete array

推荐答案

我认为您应该像这样用foreach()来迭代$events的 0 索引，

I think you should try like this way with foreach() to iterate the 0th index of $events,

foreach($events[0]['events'] as $obj) {
    print '<pre>';
    print_r($obj);
    print '</pre>';
}
