Best way to enable javascript in php?

Question

I'm doing it now.

 <?php
//show footer
echo "<script type='text/javascript'>\n";
echo "alert('Congrats');\n";
echo "</script>";

?>

Is there a better way than just repeating it?

of course

?>
alert('Congrats');
<?

Answer 2

Just put your JavaScript code outside of PHP tags:

<?php
  // your PHP code goes here
?>
// your javascript function out of the PHP tag.
function f() {
   alert('congrats');
}
