‘countryCode’ => ‘GB’,
‘mailTypes’ =>
array (
0 =>
array (
‘mailType’ => ‘MediumCorrespondence’,
‘services’ =>
array (
0 =>
array (
‘serviceType’ => ‘Tracked’,
‘weights’ =>
array (
0 =>
array (
‘name’ => ‘1-100 g.’,
‘weightFromGram’ => 1,
‘weightToGram’ => 100,
‘sendingTariff’ =>
array (
‘tariffType’ => NULL,
‘amount’ => 4.15,
‘variantId’ => 1144254,
‘includedTariffTypes’ =>
array (
0 => ‘Priority’,
),
‘requiredTariffTypes’ => NULL,
),
‘availableTariffs’ =>
array (

my code:

foreach($results as $result){
    echo '<tr>';
    echo '<td>'.$result['countryCode'].'</td>';
    echo '</tr>';
}
echo '</table>';

echo '<table>';
foreach($result['mailTypes'] as $mailtype){
    echo '<tr>';
    echo '<td>'.$mailtype['mailType'].'</td>';
    echo '</tr>';

echo '<table>';
foreach($results['services'] as $service){

     echo '<br><table>';

           foreach($results as $result): ?>
        <tr>

<td><?PHP echo $result['countryCode']; ?></td>


<td><?PHP  foreach($result['mailTypes'] as $mailtype): ?>
        <tr>

<td><?PHP echo $mailtype['mailType']; ?></td>

<td><?PHP foreach($mailtype['services']  as $service): ?>
        <tr>


<td><?PHP echo $service['serviceType']; ?></td>

<td><?PHP  foreach($service['weights']  as $name): ?>
        <tr>
           <td><?PHP echo $name['name']; ?></td>
             <td><?PHP echo $name['weightFromGram']; ?>-<?PHP echo $name['weightToGram']; ?></td>
               <td><?PHP echo $name['sendingTariff']['amount']; ?></td>

        </tr>
    <?php endforeach; ?></td>


        </tr>
    <?php endforeach; ?></td>

        </tr>
    <?php endforeach; ?></td>

        </tr>
    <?php endforeach;

                 echo '</table>';

OUTPUT:

GB  
MediumCorrespondence    
Tracked 
1-100 g.    1-100   4.15
101-250 g.  101-250 5
251-500 g.  251-500 5.25
501-1000 g. 501-1000    7.65
1001-1500 g.    1001-1500   10.75
1501-2000 g.    1501-2000   13.25
Ordinary    
1-100 g.    1-100   2.25
101-500 g.  101-500 3.8
501-1000 g. 501-1000    5.75
1001-2000 g.    1001-2000   9.7
Registered  
1-100 g.    1-100   5.6
101-500 g.  101-500 7.15
501-1000 g. 501-1000    9.2
1001-2000 g.    1001-2000   13.2

Also everything will be inserted in wp database with cron regular price update:

 $allPosts = $wpdb->get_results("SELECT * FROM wp_pastas WHERE countryCode LIKE '".$result['countryCode']."' AND amount='".$name['sendingTariff']['amount']."'");


if (count($allPosts) == 0) {

      $updated =  $wpdb->update($tablename, array('amount'=>$name['sendingTariff']['amount']), array('weightFromGram'=>$name['weightFromGram']));

               if ( $updated == 0 ) {
    $wpdb->insert( $tablename, array(
            'countryCode' => $result['countryCode'],
            'weightFromGram' => $name['weightFromGram'],
            'weightToGram' => $name['weightToGram'],
            'amount' => $name['sendingTariff']['amount'] ),
            array( '%s', '%s', '%s', '%s' )
        );
}

(Edit)

At first text u provide it’s not Json but more like output of var_dump, so at this point u can’t use json_decode at this string

Also the thing u call json ends with "," so it cannot be valid anything

If you need to parse it you can try eval but mind it can make your code vulnerable (atleast as i know) there’s some old posts about it, im not sure how if it’s still same in php 7/8
When is eval evil in php?

<?php
$arrayString = "
array(
    array(
        'countryCode' => 'GB',
        'mailTypes' => array(
            array(
                'mailType' => 'MediumCorrespondence',
                'services' => array(
                    array(
                        'serviceType' => 'Tracked',
                        'weights' => array(
                            array(
                                'name' => '1-100 g.',
                                'weightFromGram' => 1,
                                'weightToGram' => 100,
                                'sendingTariff' => array(
                                    'tariffType' => NULL,
                                    'amount' => 4.15,
                                    'variantId' => 1144254,
                                    'includedTariffTypes' => array('Priority'),
                                    'requiredTariffTypes' => NULL
                                ),
                                'availableTariffs' => array()
                            )
                        )
                    )
                )
            )
        )
    )
)";

// Your string evaluated to code
$array = eval("return $arrayString;");

// Check diffrences between diffrent output approach

var_dump($array); // Most similar to what u gave us

print_r($array); // Common output variable to text

echo json_encode($array)); // Output what u gave us but as valid json
?>
