Parsing JSON array with PHP foreach

Question

Wondering why my PHP code will not display all "Value" of "Values" in the JSON data:

$user = json_decode(file_get_contents($analytics));
foreach($user->data as $mydata)
{
     echo $mydata->name . "\n";

}        
foreach($user->data->values as $values)
{
     echo $values->value . "\n";
}

The first foreach works fine, but the second throws an error.

{
   "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"
            }, ...

Answer 1

You maybe wanted to do the following:

foreach($user->data as $mydata)      {          echo $mydata->name . "\n";          foreach($mydata->values as $values)          {               echo $values->value . "\n";          }     }         

Answer 2

You need to tell it which index in data to use, or double loop through all.

E.g., to get the values in the 4th index in the outside array.:

foreach($user->data[3]->values as $values)
{
     echo $values->value . "\n";
}

To go through all:

foreach($user->data as $mydata)
{
    foreach($mydata->values as $values) {
        echo $values->value . "\n";
    }

}
