getResponse() error while trying to send query with PHP_EOL

[marbastm]

Hi, I' am trying to send PHP_EOL (\n) symbols within my query, but I get the following error (403 Forbidden):
https://pastebin.com/pR9JEbKP

To do so I use in the input ($data) text blocks with three numbes like <666> and in TranslateClient.php in section private function getResponse($data) I use the following replacement:
$data = str_replace('<888>', PHP_EOL, $data); right before $queryArray = array_merge[..]

In the meantime, I' am able to decode the $queryBodyEncoded query with http://www.url-encode-decode.com/ and it shows that my query syntax (if it's a thing) is right (comparing to query without PHP_EOL).

So I assume that it's either Google don't like query with encoded PHP_EOL or I' am doing smth wrong.
Please help me.

I logged $queryBodyEncoded and used its result in browser and got the translation so it seems that Guzzle is returning error.

It seems that just rearragement of $data = str_replace('<888>', PHP_EOL, $data); and $tokenData = is_array($data) ? implode('', $data) : $data; solved it.
