How to use PHP session variable in Javascript?

Question

I have a .php file and .js file. I want to use the php variable in javascript file but its not working. I found a solution by using session but that didn't worked.Can anybody provide me a solution or have a look at the code if there is any mistake.

In .php

 $wd=500/$w;
 $_SESSION['wd']=$wd;

In .js

  var sf= <?php echo json_encode($_SESSION['wd']);?>;

Try var sf= '<?php echo json_encode($_SESSION['wd']);?>'; Note quotes. — Tushar

You can pass session value from php file to js by following method .

php file :-

 $wd=500/$w;
 $_SESSION['wd']=$wd;
 echo '<script>var pf = '.json_encode($_SESSION['wd']).';</script>';

Js file :-

 var sf = pf;

You can simply pass the value through PHP like

 $wd=500/$w;
 $_SESSION['wd']=$wd;
 echo '<script>var passedData = '.json_encode($_SESSION['wd']).';</script>';

And catch the the data in javascript like as

 var sf = passedData;
