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}]}
我所需要的只是从响应中提取 random1，random2，random，3，因此最终结果将是：
- 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[0] [1]将提取随机2并[2]随机3如何获得随机1，随机2，随机3，一次响应？所以最后的回声将是：
- 随机1
- 随机2
- 随机3
提前感谢您，任何帮助将不胜感激！
循环
$json['result']你所做的只是将第一个索引0 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";
}
在这里尝试一下
更新
如果你想过滤，比如说random1那么这样做
$json = json_decode($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);
$result将仅包含random2和random3
results是一个数组，所以你得到了数组中的第一个：$json["results"][0] 。
如果要迭代所有值，它应该是这样的：
foreach($json["results"] as $data) {
echo json_encode($data['response']);
}
foreach($json["results"] as $data) { echo json_encode($data['response']);}
