$curl = new Curl();
$curl->download('https://www.example.com/image.png', '/tmp/myimage.png');
echo $curl->responseHeaders['Content-Type'] . "\n"; // image/png

curl_close($curl->curl);
```

```php
require __DIR__ . '/vendor/autoload.php';

use \Curl\MultiCurl;

// Requests in parallel with callback functions.
$multi_curl = new MultiCurl();

$multi_curl->success(function($instance) {
    echo 'call to "' . $instance->url . '" was successful.' . "\n";
    echo 'response:' . "\n";
    var_dump($instance->response);
});
$multi_curl->error(function($instance) {
    echo 'call to "' . $instance->url . '" was unsuccessful.' . "\n";
