是否可以在纯JS中访问SESSION变量（在PHP中设置）？

Question

I found many answers related to ASP.NET MVC as well as PHP-related one (eg How to access PHP session variables from jQuery function in a .js file? )

However I would like to understand if it's possible (via Chrome DevTools' console or in a .HTML page) to access a variables set in PHP by:

$_SESSION['varXY'] = 'abc';

Answer 1

It is not possible to access PHP Session Variables in .html or .js files directly. However you can print/echo PHP variables in html.

If you want these variables as JS variables that can be done but it is not a good practise to do that.

Better way of accessing PHP variables in JS is via AJAX and PHP file. An example would be like below -

// sessionInfo.php
$sessions = array("var1" => $_SESSION['varXY'], "var2" => $_SESSION['abc']);
echo json_encode($sessions);

And in JS file -

$.ajax({url : sessionInfo.php, method: "get", dataType:"json" success: function(response){//Your session variable values here ...}});
