Use $_SERVER[‘HTTPS’] to check the protocol whether it is HTTP or HTTPS.

<?php
    $protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
?>

<?php

$protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";

Use $_SERVER[‘HTTP_HOST’] to get header from the current request and $_SERVER[‘REQUEST_URI’] to get URI of the current page.

<?php
    $currentURL = $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
?>

<?php

$currentURL = $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

If you want to get current page URL with query string, use this $_SERVER[‘QUERY_STRING’].

<?php
    $currentURL = $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] . $_SERVER['QUERY_STRING'];
?>

<?php

$currentURL = $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] . $_SERVER['QUERY_STRING'];
