How to pass an array within a query string?

Is there a standard way of passing an array through a query string? To be clear, I have a query string with multiple values, one of which would be an array value. I want that query string value to be treated as an array- I don't want the array to be exploded so that it is indistinguishable from the other query string variables. Also, according to this [post answer][1], the author suggests that query string support for arrays is not defined. Is this accurate?

Would it be acceptable to name multiple params the same name, and that way I would know that they belong to an array? Example: ?myarray=value1&myarray=value2&myarray=value3... Or would this be a bad practice?
