Working with Paypal cancel_return - php

Question

I'm doing my project with laravel 5 and here I have to do payment with paypal. I got this code and doing well with my payments. But when someone goto paypal and if he return without doing payment cancel_return works.It's fine. But I don't know how to handle the $_GET when return Here is my route also
Route::get('/paypal/cancel','Paypal\PaypalController#paypalCancel');
I'm using this code to move to paypal page with my sandbox account.
form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" id="paypal">
<input type="hidden" name="cmd" value="_xclick" />
<input type="hidden" name="cbt" value="Return to example" />
<input type="hidden" name="business" value="xxx#gmail.com" />
<input type="hidden" name="item_name" value="{{$data['p_name']}}" />
<input type="hidden" name="amount" value="{{$data['tot']}}">
<input type="hidden" name="button_subtype" value="services" />
<input type="hidden" name="no_shipping" value="0">
<input type="hidden" name="return" value="{{url('/paypal/return')}}" />
<input type="hidden" name="notify_url" value="{{url('/paypal/notify')}}"/>
<input type="hidden" name="cancel_return" value="{{url('/paypal/cancel')}}" />
<input type="hidden" name="currency_code" value="USD"/>
<input type="hidden" name="image_url" value="" />
<input type="hidden" id="custom" name="custom" value="{{$data['id']}}"/>
<input type="hidden" class="btn btn-primary" style="width:100%" alt="PayPal - The safer, easier way to pay online!"/>
</form>

If a user cancels payment in PayPal, the next action is up to you. You can either display a "Payment was canceled" page to inform the user that they canceled the payment, or you can prompt them to try payment again.
The cancel_return URL is purely there so developers can show a friendly message when payment has been canceled.
