class Api
{
    const API_URL = 'http://yoursite/api/v2'; // API URL/Replace reseller domain
    const API_TOKEN = ''; // Your API token

    public function order($data) { // add order
        $post = array_merge([

        $result = curl_exec($ch);
        if (curl_errno($ch) != 0 && empty($result)) {
            $result = false;
        }
        curl_close($ch);

// Fetch Packages
$packages = $api->packages();

// Check balance
$balance = $api->balance();

// Add order
$order = $api->order(array('package' => 1, 'link' => 'http://example/link', 'quantity' => 100));

// Add Custom comments order

In this code am just getting a blank page but I want to output the Public function balance () I wanna output the JSON response just help mep Me

How to output it's json_decode? Please help me

</div>

As comments have said, you need to output a Variable.

print_r($order);
print_r($status);

I'm using print_r because it gives you a nice display of an Array value. Which is most likely what you are gonna get back from your json_decode.

Side note: The current way you are using json_decode you will have to refer to variables like

$order->id

But if you want to access them as arrays

$order['id'] 

Then you need to use json_decode like this

json_decode($json, true); // The True value is important
