PHP echo JS which includes PHP variable

I have sendForm.php file, which is php using PHPMailer for sending form. In between tags there is echo and I need to use PHP variable in between tags. Is that possible somehow? I know this is too much of combining PHP and JS, but what can I do... I need a window pop-up, that's why I use also JS. The echo itself prints only to the webpage itself.

$totalSize = ($totalSize/(1024*1024));
$totalSize = round($totalSize,2);

if(!$mail->Send()) {
   echo "Error sending form! You are trying to send too large files. Their size is: ", $totalSize, " MB";
   echo '<script type="text/javascript">alert("Error sending form! You are trying to send too large files. Their size is: ??? ");</script>';
   }

How can I print $totalSize variable inside of the JS in the place of those question marks in the 2nd echo? Thanks for your help. I'm still a beginner.

PHP is a server side language, while JavaScript is a client side language. If you are trying to validate your forms on the server side without reloading the page (and let JavaScript pop up a warning), look into AJAX.

try this 

  if(!$mail->Send()) {
    echo "Error sending form! You are trying to send too large files. Their size is: ".$totalSize." MB";
        ?>
<script type="text/javascript">
alert("Error sending form! You are trying to send too large files. Their size is: <?php echo $totalSize;?> ");
</script>
<?php }

if(!$mail->Send()) {
   echo "Error sending form! You are trying to send too large files. Their size is: ". $totalSize. " MB";
   echo '<script type="text/javascript">alert("Error sending form! You are trying to send too large files. Their size is: '. $totalSize. '");</script>';
   }

//I corrected some errors in the first echo (replace comma with dot )
