Magento 2: convert curl response into array

Question

I am not able to convert magento 2 JSON response into array. Can you please help in short out this problem?

Here is my code:

$url = 'http://example.com/api/coop';
$post = [
        'firstname' => $userDetail->firstname,
        'lastname'  => $userDetail->lastname,
        'email'     => $userDetail->email,
        'password'  => $userDetail->password
    ];
$this->curlClient->post($url, $post);
$responseCurl = $this->curlClient->getBody();
print_r($responseCurl);
die();

Output:

{"coop_id":"COOP33"}

I have to use coop_id value somewhere in my logic. Thanks in advance.

Answer 1

You can check in PHP sandbox, example below.
Show example

<?php

$jsonString = '{"coop_id":"COOP33"}';

$stdClass = json_decode($jsonString);
echo $stdClass->coop_id; //COOP33

$array = json_decode($jsonString, true);
echo $array['coop_id']; //COOP33

Answer 2

 $json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));           // Object
var_dump(json_decode($json, true));     // Associative array

Answer 3

You can use json_decode as follows.

<?php
    $json = $responseCurl;    
    $array = json_decode($json, true);
    $coop_id = $array['coop_id'];
?>
