This example shows how to handle exported dashboards in a Stimulsoft Viewer for PHP. First, include the Stimulsoft libraries:

<?php
require_once '../vendor/autoload.php';

use Stimulsoft\Events\StiExportEventArgs;
use Stimulsoft\Report\StiReport;
use Stimulsoft\StiResult;
use Stimulsoft\Viewer\StiViewer;
?>

Create a Viewer object and set JavaScript options, such as the relative path and adding a favicon:

$viewer = new StiViewer();
$viewer->javascript->relativePath = '../';
$viewer->javascript->appendHead('<link rel="shortcut icon" href="/../favicon.ico" type="image/x-icon">');

Define viewer events before processing. In this example, onEndExportReport is used to save the exported dashboard file on the server:

$viewer->onEndExportReport = function (StiExportEventArgs $args) {

    // Getting the file name with the extension
    $reportName = $args->fileName;
    if (substr($reportName, -strlen($args->fileExtension) - 1) !== '.' . $args->fileExtension)
        $reportName .= '.' . $args->fileExtension;

    // If the dashboard snapshot is saved, add it to the file name
    if ($args->fileExtension == 'mrt') {
        $lastDotPos = strrpos($reportName, '.');
        $reportName = substr($reportName, 0, $lastDotPos) . "-snapshot." . substr($reportName, $lastDotPos + 1);
    }

    // Saving the exported file in the 'reports' folder
    $reportPath = "../reports/$reportName";
    file_put_contents($reportPath, base64_decode($args->data));

    // Return success or error message
    return StiResult::getSuccess("The exported dashboard has been successfully saved to '$reportPath' file.");
};

Process viewer requests on the server side using handler->process():

$viewer->handler->process();

Create a dashboard object, load the template using loadFile(), and assign it to the viewer:

$report = new StiReport();
$report->loadFile('../reports/Christmas.mrt');
$viewer->report = $report;

Finally, render the visual part of the viewer as a prepared HTML page using printHtml():

$viewer->printHtml();

In the screenshot below you can see the result of the sample code:
