get - PHP Url Parameters with Square Brackets

one text

I want to send the following json to the PHP server in a GET request

{"filters":{"abc]def":"xyz"}}

My request url looks like this

• before encode: https://test.com?filter[abc]def]=xyz
• after encode: https://test.com?filter%5Babc%5Ddef%5D=xyz

But server $_GET becomes ['filter'=>['abc'=>'xyz']]

Is there a way to make the server $_GET equal to ['filter'=>['abc]def'=>'xyz']] ?
