You simply cannot do that, you need to understand the difference between client/server side programming, you cannot assign Javascript value to PHP variable, yea but you can assign PHP value to your javascript

You cannot do that. An alternative may be creating a cookie using javascript and then read the cookie in PHP.
In Javascript:
document.cookie = "cookieName=cookieValue";
And in PHP
But an important point, for this to run the browser needs reload.
Best regards...

You can do it using ob_start[] function [documentation]. If you use this method you can call a function and parse the html content. You search for your variable and get it with php..
var var_example = "2222";

To Set PHP Variable in JavaScript, we define a JS variable and assign PHP value using PHP tag with single or double quotes.
Most of the time you have to set PHP variable value in JavaScript. If there is only simple variable like string or any integer then you can simply echo on the JS variable with PHP tag.
For example if you have a string value on the PHP variable and want to assign it and console it on JS.
varnormalText=''; console.log[normalText];
|
Output:
Lorem ipsum dolor sit amet
If you have any array value in PHP and you want to get that value on the same JavaScript variable then,
varphpArray=; console.log[phpArray];
|
Output on Console:
[3] [“Lorem”, “ipsum”, Array[2]]
0: “Lorem”
1: “ipsum”
2: [2] [“dolor”, “amet”]

- Take the PHP variable on our JS variable.
- Then we call that function with JS variable as a parameter, Which alerts the addition of numbers.
