getQueryParams not returning proper data type about laminas-diactoros HOT 1 CLOSED

Let's start with:

Same thing happens when applying parse_str($_SERVER['QUERY_STRING']).

and:

• `$client->request('GET', $myServiceUrl . '?' . http_build_query($aggregates))

We'll start with a statement: query string arguments are presented as a string; hence the verbiage "query string". This is defined by the IETF specifications.

Now, when it comes to PHP, http_build_query() creates a string representation of the arguments passed to it. parse_str() parses the string pass to it, has zero idea what the types of the arguments are, and, as such, it resolves all of the values as strings.

This is true of the behavior of $_GET as well. If you were to build a script with the following:

<?php
http_response_code(200);
header('Content-Type: text/plain');

echo var_export($_GET, true), "\n";

and then pass it a URI with the query string "?aggregates%5Bnumber%5D=1", you'd get:

array (
  'aggregates' =>
  array (
    'number' => '1',
  ),
)

Essentially, this is something we cannot change.

It's up to the developer of the application to decide what the intended types are in this scenario, validate them, and, if necessary, cast them.
