Answer 1

Just a quick idea, that could help some people:

I think (never tried) there is also a way to ask the web server (Apache, etc) to let JS files be handled as PHP content.

Advantages:

• No need to rename your JS files to .js.php
• Takes advantage of caching
• Can be applied only to a specific folder (not to every JS file of your website)

Withdraws:

• Do not forget that those "php" files are "cached" somewhere, so don't rely on the fact that files are generated every time.
• Server resources: as said in other answers, make sure to use such a trick only when it's really not possible to put PHP code outside of the JS files (using ajax queries for instance), or on files that don't load the server too much.
