How to take a screenshot or make a image of current screen using php and javascript with jquery or make a pdf file of current scrren

For create a image of current screen using javascript add below script into your file

<script type="text/javascript">
function printDiv()
{
    jQuery('.year_box').remove();
// add your container id for capcture screen here i write "main_panel_body" for example
    html2canvas([document.getElementById('main_panel_body')], {  
        onrendered: function(canvas) 
        {
            var img = canvas.toDataURL();
            jQuery('.overlay_box').show();
// calling ajax method for create image from binary data
            $.post("save.php", {data: img}, function (file) {
                jQuery('.overlay_box').hide();
            window.open("download.php?business_idsv="+business_id+"&limit="+limit+"&path="+ file,'_blank');});  
        }
    });
    jQuery('.year_box').show();        
}
</script>

Here is my save.php file

require_once("config.php");
$data = $_POST['data'];
$file =  'tempimage.png'; // here creating a temporary file

// remove "data:image/png;base64,"
$dir_to_save = "tempimage/";

$uri =  substr($data,strpos($data,",")+1);

// save to file
file_put_contents($dir_to_save.$file, base64_decode($uri));


echo $dir_to_save.$file; exit;

// save.php file end

Below is my download.php file for serve image file

<?php
$file = trim($_GET['path']);

// force user to download the image
if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: image/png');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
    readfile($file);
    unlink($file);
    exit;
}
else {
    echo "$file not found";
}

If you want to create a pdf file and add image into pdf file then use below script in download.php file

ob_start();
?>
<div class="page-top">
   Pdf report
   </div>
   <div class="image"><img src="<?php echo $file; ?>" width="750" /></div>
<?php
$html = ob_get_clean();
// here i use html2pdf library for create a pdf file
require_once(dirname(__FILE__).'/html2pdf/html2pdf.class.php');
    $html2pdf = new HTML2PDF('P','A4','en',true,'UTF-8',array(5, 5, 5, 8));
    $html2pdf->WriteHTML($html);
    $html2pdf->Output($business_info['business_name'].'.pdf','I');
ob_clean();
    flush();
    readfile($file);
    unlink($file);
    exit();
