Multiple headers with the same name

[DCzajkowski]

I am trying to connect to a server that returns three headers with the same name: Set-Cookie. When I do a simple

dd(Zttp::asFormParams()->post($url, [
    // some data
])->headers()->toArray());

it returns an array of headers, but Set-Cookie is only one there.

Expected: There should be an array of cookies returned:

[
    'Set-Cookie' => [
        'cookie-1',
        'cookie-2'
    ],
    // some other data
]

Actual: Only first cookie is returned

[
    'Set-Cookie' => 'cookie-1',
    // some other data
]

I should note that

$response->header('Set-Cookie')

works as expected by creating a comma-separated list :)

I run into the same problem. Took me quite some time to figure it out.

Is this just the use of $v[0] instead of return [$k => $v]; which is causing this?

zttp/src/Zttp.php

Lines 270 to 275 in 39f84d0

	function headers()
	{
	return collect($this->response->getHeaders())->mapWithKeys(function ($v, $k) {
	return [$k => $v[0]];
	})->all();
	}

@pxgamer this is one way to solve it. but it's a breaking change :) it will convert all values into arrays of strings instead of just strings.
i did it exactly this way, but now i can't update the package. which is fine in my case.
