Message:

I have an cURL file that will return an array like below and I wonder how can I declare the variable of [data]=>[id].I tried like $decoded.data or $decoded.[data] but it does not work.

Array

(

    [data] => Array

        (

            [id] => 2

            [email] => [email protected]

            [first_name] => Janet

            [last_name] => Weaver

            [avatar] => https://reqres.in/img/faces/2-image.jpg

        )



    [support] => Array

        (

            [url] => https://reqres.in/#support-heading

            [text] => To keep ReqRes free, contributions towards server costs are appreciated!

        )



)

PHP file:

<?php

  $ch = curl_init();

  $url = "https://reqres.in/api/users/2";

  curl_setopt($ch,CURLOPT_URL,$url);

  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

  $resp = curl_exec($ch);

  $decoded = json_decode($resp,true);

  print_r($decoded);

  curl_close($ch);

?>

My Answer:
To declare a variable from the cURL response in PHP, you can use the `json_decode` function to convert the JSON response into an associative array. Here's an example of how you can do this:

php
// Your cURL request code here

// Assuming $response contains the JSON response from cURL
$response = '{"data": {"key1": "value1", "key2": "value2"}}';

// Decode the JSON response into an associative array
$data = json_decode($response, true);

// Access the 'data' key in the array
$dataArray = $data['data'];

// Now you can access the values in the 'data' array
echo $dataArray['key1']; // Output: value1
echo $dataArray['key2']; // Output: value2


In this example, we assume that the cURL response is stored in the variable `$response`. We then use `json_decode` with the second parameter set to `true` to convert the JSON response into an associative array. Finally, we access the 'data' key in the array to get the values stored within it.
