php - php JSON解析问题

Question

我有这个 json 响应

 {"success":true,"results":[{"response":["random1"],"id":"6566","Limit":1},{"response":["random2"],"id":"6563","Limit":1},{"response":["random3"],"id":"6568","Limit":1}]}

我需要的只是从响应中提取 random1,random2,random,3，所以最终结果将是:

• 随机1
• 随机2
• 随机3

我有这个脚本

$jsonData = file_get_contents("json");

$json = json_decode($jsonData,true); 

foreach($json["results"][0]["response"] as $data) {
 {
   echo json_encode($data);

}
}

但这只会提取

• 随机1

如果我更改 [1] 中的 [0] 将提取 random2 和 [2] random3 如何立即获得 random1,random2,random3, 响应？所以最终的 echo 将是:

• 随机1
• 随机2
• 随机3

预先感谢您，如有任何帮助，我们将不胜感激!

Answer 1

循环查看您的$json['result']你所做的只是取第一个索引 0其中有random1作为其 response值

$json = '{"success":true,"results":[{"response":["random1"],"id":"6566","Limit":1},{"response":["random2"],"id":"6563","Limit":1},{"response":["random3"],"id":"6568","Limit":1}]}';
$json = json_decode($json,true); 

foreach($json["results"] as $data) {
   echo $data['response'][0]."\n";
}

更新

如果你想过滤，比如说random1然后这样做

$json = json_decode($json,true); 
$filter = array("random1"); //You can add items to filter
$result = array();
foreach($json["results"] as $data) {
   if(!in_array($data['response'][0],$filter))
       $result[] = $data;
}
print_r($result);

$result将仅包含 random2 & random3
