Simple answer: Yes!

PHP scripts are parsed by the web server before being sent out. This means that all database queries are done before any data leaves the server.

Javascript is a client side language, which means that you could simply copy+paste your javascript into a .php files, and change

setValue(0, 1, 200) 

to something like:

setValue(<?= $val1 ?>, <?= $val2 ?>, '<?= $val3 ?>');
