Question

我使用twitter ouath来获取我的推文，现在有一个数据数组，我希望使用foreach循环显示所有描述项。我怎样才能遍历一个对象（stdclass）???

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

Answer 1

与循环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/>';
  }
}

Answer 2

foreach也可以遍历对象以获取其可见属性。

Answer 3

简单如

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

如何使用foreach来回显我的数组中的描述？
