Javascript location hash into php variable

Question

Am trying to get the current URL that contains a hash e.g (http://www.example.com/index.php#folder23242%FNew). Anything after the hash the variable must store it in PHP variable. I have added the script but the PHP does not recognize the Javascript variable value and prints no value. I need it to take the Javascript variable so it can execute my php script.

echo '<script>
var url = ""; 
url = location.hash;
url = decodeURI(url);
document.cookie="currenturl=url";
</script>';
$url = "";
$url = $_COOKIE["currenturl"];
$arr = explode('/', $url);
$url = end($arr);

echo "<script>alert('".$url."')</script>";

PHP is Server Side and JS is client side. JS will always execute (on client side) after PHP(on server side). How are you expecting this to work. — Umair Khan, Nov 20 '19 at 06:08
PHP does not get URL that values that contain a # even if you USE "REQUEST URI" etc hence the use of Javascript. Unless there is a to? — saiyan101, Nov 20 '19 at 06:14

Impossible to get hash from current url.

$_SERVER['REQUET_URI'] only contains path and query string.

The browser does not send the fragment to the server.

Answer is 'Standard methods will not help you."

You can set it in your cookie with document.cookie="currenturl=location.toString()";

Then access it from your php code,

$url = $_COOKIE["currenturl"];
echo parse_url($url)["fragment"];

Example:

php > print_r(parse_url("https://example.com/#folder"));
Array
(
    [scheme] => https
    [host] => example.com
    [path] => /
    [fragment] => folder
)
