how to make javascript in to PHP

Question

I have the following javascript code which I need to be executed in a PHP file. I need to know how should I enter the php tags to this javascript code.

I am new to web programming.

The javascript used here is to export content in the html page to a .csv file.

Answer 1

use this, add ?> before it and <?php after script

<?php 
/* your php code */
?>
<script type='text/javascript'>
// your script 
</script>
<?php 
/* your php code */
?>

Answer 2

Top answer from a previous question

<script type="text/javascript">
var my_var = <?php echo json_encode($my_var); ?>;
</script>

works if you define and use the variable in PHP, and want to pass the variable in the Javascript. If you are running in a PHP file (which you are) you can also use

function foo()
{
    var i = 0 ;
    i = <?php echo $my_var; ?>
}
