Пример отправки файла CURL PHP

Пример отправки файла полученного методом POST на другой хост через CURL на PHP:

if (isset($_FILES["importXls"]) && $_FILES["importXls"]["tmp_name"] != "") {
	$boundary = "------------------------" . md5(mt_rand() . microtime());
	$postData = "--{$boundary}\r\n" .
				"Content-Disposition: form-data; name=\"file\"; filename=\"" . $_FILES["importXls"]["name"] . "\"\r\n" .
				"Content-Type: " . $_FILES["importXls"]["type"] . "\r\n\r\n" .
				file_get_contents($_FILES["importXls"]["tmp_name"]) . "\r\n\r\n" .
				"--{$boundary}--\r\n";
	//print_r($postData);die();
	$headers = [
		"Content-Type: multipart/form-data; boundary={$boundary}",
		"Accept: application/json",
		"Authorization: token TOKEN, "")
	];
	$ch = curl_init();
	$options = [
		CURLOPT_URL => "https://HOST/api/test",
		CURLOPT_HEADER => false,
		CURLOPT_POST => true,
		CURLOPT_CUSTOMREQUEST => "POST",
		CURLOPT_HTTPHEADER => $headers,
		CURLOPT_POSTFIELDS => $postData,
		CURLOPT_RETURNTRANSFER => true,
		CURLOPT_VERBOSE => false,
		CURLOPT_SSL_VERIFYPEER => false,
		CURLOPT_SSL_VERIFYHOST => false,
		CURLOPT_FOLLOWLOCATION => true,
		CURLOPT_ENCODING => "gzip"
	];
	curl_setopt_array($ch, $options);
	$responce = curl_exec($ch);
	if (!curl_errno($ch)) {
		$info = curl_getinfo($ch);
		if ($info["http_code"] != 200) {
			$return = [
				"status" => "fail",
				"message" => "File uploaded successfully",
				"error" => json_decode($responce, true)
			];
			$errorParce = true;
		}
	} else {
		$return = [
			"status" => "fail",
			"message" => curl_error($ch)
		];
		$errorParce = true;
	}
	curl_close($ch);
	$responce = json_decode($responce, true);
}

Результат запроса подразумевается, что будет в формате JSON и будет получен в переменную $responce.
