How to assign javascript variable in a php variable inside javascript function

[eluser]Shiju S S[/eluser]
I got it with the following jsscript code

Code:

var count="<?php echo $ctr;?>";
   var a=new Array;
   <?php
    for($i=0;$i<count($c_purpose); $i++)
    {
     echo "a[$i]='".$c_purpose[$i]."';\n";
    }
    ?&gt;

where $ctr and $c_purpose are php variables
