$apiKey = urlencode('***************');
 
    // Prepare data for POST request
    $data = array('apikey' => $apiKey);
 
    // Send the POST request with cURL
    $ch = curl_init('https://api.textlocal.in/balance/');
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

This is how you access the data:

$response = '{ "balance":{ "sms":1852 }, "status":"success" }';
$object = json_decode($response);
echo $object->balance->sms;
// 1852
