想知道为什么我的PHP代码不会在JSON数据中显示“值”的所有“值”:
$user = json_decode(file_get_contents($analytics)); foreach($user->data as $mydata) { echo $mydata->name . "\n"; } foreach($user->data->values as $values) { echo $values->value . "\n"; }
第一个foreach工作正常,但第二个抛出错误。
{ "data": [ { "id": "MY_ID/insights/page_views_login_unique/day", "name": "page_views_login_unique", "period": "day", "values": [ { "value": 1, "end_time": "2012-05-01T07:00:00+0000" }, { "value": 6, "end_time": "2012-05-02T07:00:00+0000" }, { "value": 5, "end_time": "2012-05-03T07:00:00+0000" }, ...
您可能想要执行以下操作:
foreach($user->data as $mydata) { echo $mydata->name . "\n"; foreach($mydata->values as $values) { echo $values->value . "\n"; } }
