<?php
$params = array(
    "card" => array(
        "name" => "Card Name",
        "number" => "4242424242424242",
        "exp_month" => "12",
        "exp_year" =>  "19",
        "cvc" => "123"
    )
);

$create = CreateToken::create($params);
CreateToken::prettyPrint($create);

if ($create["code"] == 200) {
    $get = CreateToken::get($create["response"]->id);
    CreateToken::prettyPrint($get);
}

class CreateToken {
    private static $key = "sk_test_...................";

    static function create($params)
    {
        $url = "https://api.stripe.com/v1/tokens";

        $headers[] = "Authorization: Bearer " . self::$key;
        $headers[] = "Content-Type: application/x-www-form-urlencoded";

        return makeCurlCall($url, "POST", null, $params, $headers);
    }

    static function get($id)
    {
        $url = "https://api.stripe.com/v1/tokens/$id";

        $headers[] = "Authorization: Bearer " . self::$key;
        $headers[] = "Content-Type: application/x-www-form-urlencoded";

        return makeCurlCall($url, "GET", null, null, $headers);
    }

    static function prettyPrint($data)
    {
        echo "<pre>";
        print_r($data);
        echo "</pre>";
    }
}

Below is output for error response:
