Piwik API - get an autostart.session error (1 reply)

I am having problems with using the API. I am trying to include some API calls into a Yii framework application but i get the following error: session has already been started by session.auto-start or session_start()

I did a forum search, checked that the folders are writable,session.auto_start 0, etc. Same results.

Tested the solution found here still get the error.

When I call the file outside of the Yii app everythings works ok, but now within the application.

Code below:

<?php
use Piwik\API\Request;
use Piwik\FrontController;

define('PIWIK_INCLUDE_PATH', realpath('\wamp\www\piwik'));
define('PIWIK_USER_PATH', realpath('\wamp\www\piwik'));
define('PIWIK_ENABLE_DISPATCH', false);
define('PIWIK_ENABLE_ERROR_HANDLER', false);
define('PIWIK_ENABLE_SESSION_START', false);
require_once PIWIK_INCLUDE_PATH . "\index.php";
require_once PIWIK_INCLUDE_PATH . "\core\API\Request.php";
// if you prefer not to include 'index.php', you must also define here PIWIK_DOCUMENT_ROOT
// and include "libs/upgradephp/upgrade.php" and "core/Loader.php"


FrontController::getInstance()->init();

// This inits the API Request with the specified parameters
function piwikRequest($piwikSiteId,$piwikMethod,$piwikPeriod,$piwikDate)
{
  $piwikGetData = new Request
  ('
    method='. $piwikMethod .'
    &idSite='. $piwikSiteId .'
    &period='. $piwikPeriod .'
    &date='. $piwikDate .'
   &segment=customVariableName1==Mailing
    &format=php
    &serialize=1
    &token_auth=token
  ');
  $piwikGetData = $piwikGetData->process();
  return $piwikGetData;
}

?>

<?php 
function vizite()
{
$piwik = piwikRequest('1','VisitsSummary.getVisits','month','last1');
$arr = unserialize($piwik);
$vizite= reset($arr);
echo $vizite;
}
 ?>

Any clues ?
