How to make this request in execute? I always did file_get_contents but it takes a long time to load and frequent requests come up with such an error.

$usersad = json_decode(file_get_contents("https://api.vk.com/method/users.get?user_ids={$_SESSION['user_id']},{$idadminsurlecode}&name_case=acc&v=5.67"), true);

Answer 1

If you use your personal key for everything, then you need to write an API that will accept input parameters as you like, and then make requests to VK API. In this case, you can implement key enumeration (and the restrictions apply to the key, not to ip). And there to implement execute.
How to write the execute request itself is well described in the documentation, js like syntax.

How to make this request in execute

execute is 25 requests.
As I understand it, your site has a stupid parsing of users in the (accusative - acc) case.
What exactly needs to be collected?
What requests go to VK and how much?
