如何自定义json响应？

Question

I request a JSON query and get the output, I want to parse that output and show it in tabular form also want to insert it into database.

I performed following php code to get array representation of JSON data.

echo '<pre>';
print_r( json_decode( $result ) );
echo '</pre>';

and I get following output:

stdClass Object
(
[request] => stdClass Object
    (
        [Target] => Affiliate_Report
        [Format] => json

I want to display above data into tabular form.

Code used by me:

$result = file_get_contents($base);

$obj = json_decode($result, true);

<?php foreach ($obj['response'] as $licenseElement) :?>
<tr>
  <td><?php echo $licenseElement->data->Offer->name; ?></td>
  <td><?php echo $licenseElement->Stat->payout; ?></td>
  <td><?php echo $licenseElement->Stat->sale_amount; ?></td>
  <td><?php echo $licenseElement->Stat->datetime; ?></td>
</tr>
<?php endforeach; ?>

This code returns me an error Trying to get property of non-object everywhere at echo syntax.

Please help me to parse the above json output and display it in proper tabular format.

Answer 1

you are iterating over wrong object, you need to loop over $obj->response->data->data object to get what you are seeking

<?php foreach ($obj->response->data->data as $licenseElement) :?>
<tr>
  <td><?php echo $licenseElement->Offer->name; ?></td>
  <td><?php echo $licenseElement->Stat->payout; ?></td>
  <td><?php echo $licenseElement->Stat->sale_amount; ?></td>
  <td><?php echo $licenseElement->Stat->datetime; ?></td>
</tr>
<?php endforeach; ?>

Answer 2

You are not getting to the right level in the object hierarchy. Try with

foreach($obj->response->data->data as $licenseElement) { ... }

Answer 3

$result = file_get_contents($base);

$obj = json_decode($result, true);

<?php foreach ($obj['response']->data->data as $licenseElement) :?>
<tr>
  <td><?php echo $licenseElement->data->Offer->name; ?></td>
  <td><?php echo $licenseElement->Stat->payout; ?></td>
  <td><?php echo $licenseElement->Stat->sale_amount; ?></td>
  <td><?php echo $licenseElement->Stat->datetime; ?></td>
</tr>
<?php endforeach; ?>

This code should work. What you are trying to do is that you have considered the response as an array but the print_r functions lets us know wether your data is an array or an object.

It says StdClass Object thats why we need the "->" sign to refer to it.

All i have changed is the foreach($obj['response']->data->data as $licenseElement)

We also need to check the levels , here we are 3 levels in. :)

Hope this helps.
