如何在PHP中回显或打印数组？

Question

我有这个数组

Array
(
  [data] => Array
    (
      [0] => Array
        (
          [page_id] => 204725966262837
          [type] => WEBSITE
        )

      [1] => Array
        (
          [page_id] => 163703342377960
          [type] => COMMUNITY
        )
      )
)

我的问题是，如果没有这种结构，我怎么能回显内容呢？我试过了

foreach ($results as $result) {
    echo $result->type; 
    echo "<br>";
}

Answer 1

这会做

foreach($results['data'] as $result) {
    echo $result['type'], '<br>';
}
