用PHP foreach解析JSON数组
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 $values->value . "\n";
}
第一个foreach工作正常,但第二个抛出错误。
{ "data": [
{
"id": "MY_ID/insights/page_views_login_unique/day",
"name": "page_views_login_unique",
"period": "day",
"values": [
{
"value": 1,
"end_time": "2012-05-01T07:00:00+0000"
},
{
"value": 6,
"end_time": "2012-05-02T07:00:00+0000"
},
{
"value": 5,
"end_time": "2012-05-03T07:00:00+0000"
}, ...
回答:
您可能想要执行以下操作:
foreach($user->data as $mydata) {
echo $mydata->name . "\n";
foreach($mydata->values as $values)
{
echo $values->value . "\n";
}
}
