适用于PHP的SSRS SDK：不适用于PHP 5.5

I'm using the SSRS SDK For PHP which has not been updated since years surprisingly (08.04.2010) . It works fine under PHP 5.4 (5.4.44) but not under 5.5+ (5.5.37, 5.6.28, 7.x)

The error is :

array ( )Failed to connect to Reporting Service Make sure that the url (https://myHost:60004/ReportServer/) and credentials are correct!

The exception is thrown in line 207 because the var $content is equals to FALSE (so can't load the content).

It's perfectly fine with PHP 5.4.44.

I can't find the "SSRS SDK For PHP" documentation regarding the PHP version supported...

I'm not using any framework such as Symfony2, CakePHP, Zend Framework,... except Bootstrap.

Does anyone know or have figured out this issue?

EDIT

As asked in a comment, here is my code :

function buildSSRSReport($companyId)
    {
        require_once '../tools/SSRSReport/SSRSReport.php';

        try {
            // Create a connection to the SSRS Server
            $rs = new SSRSReport(new Credentials(SSRS_USER_ID, SSRS_PASSWORD), SSRS_REPORT_SERVER_URL);
            $sqlConnection = self::getSqlConnection();

            // Load the report and specify the params required for its execution
            $executionInfo = $rs->LoadReport2(self::getSSRSEnvironment(), NULL);
            $parameters = array();
            $parameters[0] = new ParameterValue();
            $parameters[0]->Name = "CompanyId";
            $parameters[0]->Value = $companyId;
            $rs->SetExecutionParameters2($parameters);

            // Require the Report to be rendered in HTML format
            $renderAsHTML = new RenderAsPDF();

            // Set the links in the reports to point to the php app
            //$renderAsHTML->ReplacementRoot = getPageURL();

            // Set the root path on the server for any image included in the report
            //$renderAsHTML->StreamRoot = './images/';

            // Execute the Report
            $result_html = $rs->Render2($renderAsHTML,
                PageCountModeEnum::$Actual,
                $Extension,
                $MimeType,
                $Encoding,
                $Warnings,
                $StreamIds);

            $pdfFileName = self::getCompanyAlias($sqlConnection, $companyId) . ".pdf";

            header('Content-Type: application/x-download');
            header('Content-Disposition: attachment; filename="' . $pdfFileName . '"');
            header('Cache-Control: private, max-age=0, must-revalidate');
            header('Pragma: public');

            return $result_html;
        } catch (SSRSReportException $serviceException) {
            echo $serviceException->GetErrorMessage();
        }

    }

    function getSSRSEnvironment()
    {
        return "/DEV/CompanyESGReportingServices-DEV/Main";
    }

    private function getSqlConnection()
    {
        require_once("../inc/eth_connexion.php");
        /* These 4 variables are contained within the eth_connexion.php file */
        $serverName = SQL_SERVERNAME;
        $userName = SQL_USERNAME;
        $dbName = SQL_DATABASENAME;
        $password = SQL_PASSWORD;

        // SQLSRV : Connection array used when calling SQL via sqlsrv_query
        $connectionInfo = array("Database"=> SQL_DATABASENAME,
            "UID"=> SQL_USERNAME,
            "PWD"=> SQL_PASSWORD,
            "ReturnDatesAsStrings" => true);

        $sqlConnection = sqlsrv_connect($serverName, $connectionInfo);
        if (!$sqlConnection) {
            die('Can't log to the database');
        }

        return $sqlConnection;
    }

And here is the source code of the SSRSReport constructor (original from the SSRS SDK For PHP) :

public function SSRSReport($credentials, $url, $proxy = null)
{        
    $this->_BaseUrl = ($url[strlen($url) - 1] == '/')? $url : $url . '/';
    $executionServiceUrl = $this->_BaseUrl . self::ExecutionService;
    $managementServiceUrl = $this->_BaseUrl . self::ManagementService;

    $options = $credentials->getCredentails();
    $stream_conext_params = array( 'http' =>
                                     array('header' =>
                                      array($credentials->getBase64Auth())));
    if(isset($proxy))
    {
        $options = array_merge($options, $proxy->getProxy());
        $stream_conext_params['http']['proxy'] = 'tcp://' .
                                                    $proxy->getHost() .
                                                    ':' .
                                                    $proxy->getPort();
        if($proxy->getLogin() != null)
        {               
            $stream_conext_params['http']['header'][1] = $proxy->getBase64Auth();
        }            
    }

    /**

    $context = stream_context_create($stream_conext_params);
    $content = @file_get_contents($executionServiceUrl, false, $context);
    if ($content === FALSE) // I'M GOING HERE WITH PHP 5.5+ 
    {
        throw new SSRSReportException("",
                    "Failed to connect to Reporting Service  <br/> Make sure " .
                    "that the url ($this->_BaseUrl) and credentials are correct!");
    }

    $this->_soapHandle_Exe =  new SoapClient ($executionServiceUrl, $options);
    $this->_soapHandle_Mgt =  new SoapClient ($managementServiceUrl, $options);
    $this->ClearRequest();
}

The exact error message is :
