PeterssonJesper gave you a good answer. Also, the php will always run on the server before the javascript on the client runs ... or does not run.Yogi– Yogi2015-12-29 12:33:49 +00:00Commented Dec 29, 2015 at 12:33

The PHP code runs on the server, meanwhile the Javascript code runs on the client. The PHP code will always run, no matter of what Javascript you try to surround it with.

PHP is a server side scripting so that is always run let me explain it with code.
There is no issue for PHP script code work with js. just you need to do this in .php file only.
For example:
example.php
<?php
//Initialize PHP variable value...
$htmlString= 'Hello testing'; ?>
<!-- Use PHP variable into JS -->
<script type="text/javascript">
// notice the quotes around the ?php tag
var htmlString="<?php echo $htmlString; ?>";
alert(htmlString);
</script>
And this will prompt message "Hello testing".
Hope this help you!

Yes dear, Your PHP code will run always. as PHP is server side wheres JavaScript is Client side. so when you called page Both method run simultaneously. so no matter if you defined PHP code inside JavaScript.

If you want to write php code inside javascript then you can write like following :
var message_from = <?php echo $_SESSION['user']['user_id'] ?>;

If it is inside a PHP tag and inside a PHP file, it will run the code, no matter what or where it is.
