Reply to discussion (solution)

PHP is not the value of JS, but the value of JS passed to the server! The front end can typically pass data to the backend in two ways: Post GET

$user = $_post[' user ']; Get post value in PHP $pass = $_get[' pass '); Get a Get value in PHP

And the value of the pass is generally passed through the Ajax way!
So it is not PHP to get the value of JS, but JS to pass the data to the server, and then PHP read the post get global array!

What you say is generally used in Ajax, the order in which the pages are executed is to wait until the PHP language parsing is complete before parsing the HTML code,

Are you writing HTML PHP and JS together? It is recommended to separate each file!

First, the order of execution of the server and client is clear.
PHP is a service-side language
And JS is the client's script

The service end will be done before the client, so you have to let the server to get the value of the client, the only way is to let the client send the request to the server
Like using AJAX to request
