How can I use foreach to echo the descriptions in my array?

本文关键字：描述数组何使用 foreach | 更新日期: 2023-09-27

我使用twitter输出来获取我的tweet，现在有一个数据数组，我想使用foreach循环显示所有描述项。我如何循环通过一个对象(stdclass)??

array(7) { 
[0]=> object(stdClass)#25 (19) { 
    ["geo"]=> NULL 
    ["truncated"]=> bool(false) 
    ["id_str"]=> string(18) "147102180648824832"

与遍历数组的方式完全相同，除了使用对象表示法访问属性。

foreach($tweets as $tweet) {
  echo $tweet->description;
}

或

foreach($tweets as $tweet) {
  foreach($tweet as $field => $value) {
    echo $field . ': ' . $value . '<br/>';
  }
}

foreach还可以遍历对象，查找其可见属性。

简单的

foreach( $tweets as $tweet ) {
    echo $tweet->description;
}
