Inserting php code inside a javascript method

Question

If I write php code inside a javascript method does the php code execute if the method of the javascript is not called at all ?

Answer 1

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.

Answer 2

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!
