Answer 1

CURLOPT_POSTFIELDS => http_build_query($postArray) not working

curl_setopt($cURLConnection, CURLOPT_POSTFIELDS => http_build_query($postRequest1));

Answer 2

Set Content-Type in header to application/x-www-form-urlencoded. Use like this :

        $curl = curl_init();
    curl_setopt_array($curl, array(
        CURLOPT_URL => "http://url.com",
        CURLOPT_CUSTOMREQUEST => "POST",
        CURLOPT_POSTFIELDS => http_build_query(['message' => test]),
        CURLOPT_HTTPHEADER => array(
            'Content-Type: application/x-www-form-urlencoded'
        ),
    ));
