Outbound efax developer api request using EHttpClient Yii not working - php

Question

I'm using EHttpClient extension yii.
My Code:
$file = file_get_contents($path, true);
Yii::import('ext.EHttpClient.*');
$client = new EHttpClient('https://secure.efaxdeveloper.com/EFax_WebFax.serv', array(
'maxredirects' => 3,
'timeout' => 30,
'Content-Type' => 'application/x-www-form-urlencoded',
'adapter' => 'EHttpClientAdapterCurl'));
$client->setParameterPost(array('id'=>urlencode("2313125942"), 'xml'=>urlencode($file)));
SiteHelper::printShow($client);
$response = $client->request("POST");
var_dump($response->isSuccessful());
SiteHelper::printShow($response);
My xml data:
<?xml version="1.0"?>

I already read the documentation from https://secure.efaxdeveloper.com/downloads.jsp Outbound already set all the required fields on xml data and request post. But I always get this error from efax developer API:
Post Unsuccessful!
Your request has failed due to invalid data.
Please refer to our documentation prior to resubmitting.
Error Level: User
Error Message: XML data argument was not passed.
Please contact us at 888-278-8666 if you continue to encounter errors.
Error Message : XML data argument was not passed What is wrong with my xml data?
(*Note on my request the xml post parameter is set the encoded file contents of my xml).

Answer 1

I used PHP efax instead.
PHP eFax is a PHP class that wraps the eFax® Developer API. Use PHP
eFax to automate the task of sending and receiving faxes
electronically from your PHP-powered web server.

Answer 2

Don't use urlencode. Just set the content type to application/x-www-form-urlencoded.
