Convert PHP array into Javascript array

I got a chance to write a script that converts php array into javascript  array.
Here it is..
<?php
  $phparray= array(1,2,3,4,5);
?>

<script type="text/javascript" language="javascript">
    var mydata = new Array (
    <?php
      for ($i = 0; ($i < count($phparray)); $i++) {
        if ($i > 0) {
          echo ",\n";
        }
        echo "    \"";
        echo $phparray[$i];
        echo "\"";
      }
     
    ?>
    );
</script>
