如何在此页面中遍历并显示 from_user 和文字属性：
使用此代码？：
$json = json_decode(file_get_contents('http://search.twitter.com/search.json?q=stackexchange'));
foreach($json as $obj){
var_dump($obj);
}
这是此页面的var_dump（）：

答案 1 :(得分：1)
有一组对象，每个对象都包含from_user和text属性，这些属性存储在名为results的数组中。您可以循环此数组并获取如下属性：
$json = json_decode(file_get_contents('http://search.twitter.com/search.json?q=stackexchange'));
foreach($json->results as $result){
$from_user = $result->from_user;
$text = $result->text;
echo $from_user . ' ' .$text;
}
