What happened?

After updating from CodeIgniter 4.4.8 to 4.5.4, a curl call started throwing an exception

    "title": "TypeError",
    "code": 500,
    "message": "hex2bin(): Argument #1 ($string) must be of type string, int given",
    "file": "/var/www/html/api-id/vendor/codeigniter4/framework/system/HTTP/URI.php",
    "line": 1180,

Steps to Reproduce

try to make a curl request with the following code

        $curl = service('curlrequest');
        $curl->request('GET', '', ['baseURI' => 'http://localhost:8080?startAt=0&limit=10']);

Expected Output

The curl request should work if the baseURI provided is reachable

Anything else?

errorLog.txt

The problem comes from the code found in protected function parseStr(string $query): array since the addition of declare(strict_types=1); in the file /vendor/codeigniter4/framework/system/HTTP/URI.php
A parameter named startAt once hexed gives a hex value of 73746172744174 which is not interpreted as a string in the foreach found on line 1179

---

One way to avoid this problem is to fill the url parameter correctly with the url instead of passing through the options
ex: $curl->request('GET', 'http://localhost:8080?startAt=0&limit=10', []);

---

A possible fix would be to cast $key as a string on line 1180 $return[hex2bin((string)$key)] = $value;
Another would be to remove the declare(strict_types=1); (not recommended)

I think the following is a way to go.
