PHP - generating JavaScript

The best approach is to think Javascript as PHP code.

The basic steps are:

1. Create a .htaccess file that redirects all JS files (.js) to a index file.
2. In this index file load JS file as a PHP module (require "script/$file")
3. Modify all JS files as you need. Now you can embed PHP code.

For instance, add to your .htaccess this line:

RewriteRule \.js$ index.php

In your index.php file put something like this:

// Process special JS files
$requested = empty($_SERVER['REQUEST_URI']) ? "" : $_SERVER['REQUEST_URI'];
$filename = get_filename($requested);
if (file_ends_with($requested, '.js')) {
     require("www/script/$filename.php");
     exit;
}

And finally in your file.js.php you can embed PHP, use GET and POST params, etc:

var url = "";
var params = "";

function xxxx().... 
....

In addition, a trick to skip file cache is to add a random number as javascript parameter:

Also, as said in a comment, if your webserver don't allow to modify the .htaccess, you can just ask for the PHP file directly:
