Php json: Take specific values from an API in Json and display them through a php script

Question

I am working with an API and would like to "get" some values of the same as this in JSON format. At first I researched some questions similar to mine, but unfortunately I still could not find a right way to do this:

1. Json path to get api value
2. How to catch a JSON from a URL?
3. Get JSON result with php
4. How to print a specific JSON value in PHP

In case I’m using the following Curl code in php to get the data from the API:

<?php

$token = "TOKEN_PROD";

$ch = curl_init('URL_DA_API');

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
   'Content-Type: application/json',
   'Authorization: Bearer ' . $token
   ));

$data = curl_exec($ch);
$info = curl_getinfo($ch);

echo $data;

curl_close($ch);

?>

When the above script is executed, the command echo $data; displays the following values from the API:

      "total":1,
      "limit":30,
      "offset":0

   ]
}

However, according to the JSON response above the API, I would like the PHP script to only return some objects as below:

1. id
2. date_created
3. total_payment_amount
4. payment_method_id
5. status_detail

I tried to insert the code below in the php script to get an idea of how I could solve this issue:

$json = json_decode($data);
echo $json->results->id[0];

In case how can I make the php script only display the values I mentioned above? Thanks in advance.

Answer 1

When decoded Results is an array. So I believe it should look like this:

$json = json_decode($data);
echo $json->results[0]->id;
echo $json->results[0]->date_created;
echo $json->results[0]->transaction_details->total_paid_amount;
echo $json->results[0]->payment_method_id;
echo $json->results[0]->status_detail;

When it comes to decoded json manipulation I recommend giving a var_dump in the $json to better visualize.
