Lately I've come across yet another way of putting JS code inside PHP code. It involves Heredoc PHP syntax. I hope it'll be helpful for someone.

After closing the heredoc construction the $script variable contains your JS code that can be used like this:

The profit of using this way is that modern IDEs recognize JS code inside Heredoc and highlight it correctly unlike using strings. And you're still able to use PHP variables inside of JS code.
