This looks perfectly fine.
There are a few things you have to be careful with:
- php strings can handle line endings, consider if you have:
$text = "Hello\nWorld";
echo alert('". $text ."');
You will end up with a javscript error.
- A typical javascript file that resides on on a webserver will
only be requested once from the webserver (pending cache
settings) so resources for a page load will be minimal. If you
have a php script output javascript, the browser will request
the file on each request.
