You have to remember that if JS and PHP live in the same document, the PHP will be executed first [at the server] and the JS will be executed second [at the browser]--and the two will NEVER interact [excepting where you output JS with PHP, which is not really an interaction between the two engines].
With that in mind, the closest you could come is to use a PHP variable in your JS:
var a = ''; //outputting string foo in context of JS //must wrap in quotes so that it is still string foo when JS does execute //when this DOES execute in the browser, PHP will have already completed all processing and exitedOutput:
Method 2: Using Cookies to store information:
Client Side: Use Cookie to store the information, which is then requested in the PHP page. A cookie named gfg is created in the code below and the value GeeksforGeeks is stored. While creating a cookie, an expire time should also be specified, which is 10 days for this case.
// Creating a cookie after the document is ready
$[document].ready[function [] {
createCookie["gfg", "GeeksforGeeks", "10"];
}];
// Function to create the cookie
function createCookie[name, value, days] {
var expires;
if [days] {
var date = new Date[];
date.setTime[date.getTime[] + [days * 24 * 60 * 60 * 1000]];
expires = "; expires=" + date.toGMTString[];
}
else {
expires = "";
}
document.cookie = escape[name] + "=" +
escape[value] + expires + "; path=/";
}
Server Side[PHP]: On the server side, we request for the cookie by specifying the name gfg and extract the data to display it on the screen.
