Problem with &?

Question

PHP

Hello.

I work with api vk, I ran into a problem.

When testing on local, everything works fine, but when I uploaded it to the server, I started getting an error.

There is a line for getting a token:

$token = json_decode(file_get_contents(urldecode('https://oauth.vk.com/access_token?client_id='.$appId.'&redirect_uri='.$url.'&client_secret='.$secretKey.'&code='.$_GET['code'])), true);

Everything is ok on the local, but on the server the following line is received in the response:

https://oauth.vk.com/access_token?client_id=...&redirect_uri=...&client_secret...

Those. Somehow appeared here &

Please tell me how to fix this?
