The easiest method is probably this:
- put the following in file.php
<?php
// text/javascript, not text/html
header("Content-type: text/javascript");
// your script
?>
- don't link to file.php, but to file.php/javascript.js
This way, you've got everything a browser could ever want:
- the correct Content-type-header
- it even has a .js-extension
