Use AJAX to pass information to the server-side. See also https://stackoverflow.com/questions/13840429/what-is-the-difference-between-client-side-and-server-side-programming — Teemu, Feb 24 '18 at 11:20

There is difference between Javascript and PHP, PHP is a server-side script language while Javascript is a client-side script language. See https://www.sqa.org.uk/e-learning/ClientSide01CD/page_18.htm

Use the advantage of AJAX instead for your problem
