Can I put PHP code inside Javascript .js file?

Hi,
I have a javascript .js file, can I have php code like <?=$myvar;?> inside the .js file? will it work?
many thanks.

If your server is set to parse .js as php, then yes.
Otherwise, you can change the filename to .php and that will work too...

Either will work, as long as it's parsed. Example .htaccess:

<Files file.js>
ForceType application/x-httpd-php
</Files>
