parse nordpool nested JSON data to php string using decoded_json - php

Question

The goal here is to have the Name Printed followed by the values
IE Tromsø: 33,28 30,00
Im very novice at this and have been struggling with this one for a few days trying to lookup nested PHP examples and just gives me an error
<?php
$people_json = file_get_contents('https://www.nordpoolgroup.com/api/marketdata/page/10?currency=,,,EUR');
$decoded_json = json_decode($people_json, true);
$data = $decoded_json['data'];
$filter = "Tromsø";
foreach($row as $Rows) {
echo( $filter.": " );
foreach($Columns as $row['Columns']) {
if($filter==$Columns['Name'])
{
echo($Columns['Value']. " ");
}
}
}
?>```

Answer 1

Your foreach statements are the wrong way around; it should be
foreach ($array as $value)
where you have
foreach ($value as $array)
Once you correct that, your code works fine (with some minor cleanup):
$decoded_json = json_decode($people_json, true);
$data = $decoded_json['data'];
$filter = "Tromsø";
echo( $filter.": " );
foreach ($data['Rows'] as $row) {
foreach ($row['Columns'] as $column) {
if ($filter==$column['Name']) {
echo $column['Value']. " ";
}
}
}
Output (for the first two rows of the data):
Tromsø: 33,28 30,00
