Json在Php Foreach中解析

Question

我有一个json数据，但我无法解析，因为第一个类型没有名称。

[ 
{"id":325,"distance":239,"text":"test","position":{"lat":2,"lon":3}}, 
{"id":333,"distance":123,"text":"test","position":{"lat":2,"lon":3}}, 
{"id":331,"distance":1,"text":"test","position":{"lat":2,"lon":3}} 
    ] 

PHP代码

$jsonurl = "url address"; 
$json = file_get_contents($jsonurl); 

$obj = json_decode($json,true); 

$it = "<ul>" 
    foreach ($obj[0] as $list) 
    { 
     $it .= "<h4>".$list['id']."</h4>" 
    } 

Answer 1

其stdClass Object不是array，所以访问这个样子，

$it .= "<h4>".$list->id."</h4>"; 

，改变你的for循环这样

foreach ($obj as $list) 
      ^remove [0] here 

最后你的循环是这样的，

foreach ($obj as $list) 
{ 
    $it .= "<h4>".$list->id."</h4>" 
}
