是否有一种简单的方法来替换Symfony 2中的referer中的url参数？

Question

I am trying to update a parameter in my referer url:

$referer = $request->headers->get('referer');

For example, $referer is an url whith two parameter:

string(96) "http://<my_url>/web/app_dev.php/urlpart/?param1=value1&param2=value2"

I'd like to easyly replace param1=value1 by param1=updatedvalue1 for example with another one.

I know we can do this with twig with the current request url:

{{ path(app.request.attributes.get('_route'),
   app.request.query.all|merge({'sort': 'address'})) }}

Is it possible to do the same thing in a Symfony 2 controller to update the referer?

I have found a solution with preg_replace function in PHP, I hope there is a better way to do it seems ugly, I am trying to find a better solution, any help will be apprecied!

$referer = preg_replace('/([?&])(param1)=\w+(&|$)/', '', $referer);
$referer = preg_replace('/(param2)=\w+(&|$)/', '', $referer);

Thank you for your help !

This should work:

$oldReferer = 'http://<my_url>/web/app_dev.php/urlpart/?param1=value1&param2=value2';
$newReferer = Request::create($oldReferer, 'GET', array('param1' => 'updatedvalue1'))->getUri();
