[SOLVED] Header Redirect Not Working

<?php

    require_once("../inc/config.php");
    require_once(ROOT_PATH . "inc/products.php");

    $current_page = "";

    if (empty($_GET["pg"])) {
        $current_page = 1;
    } else {
        $current_page = $_GET["pg"];
    }

    $total_products = get_products_count();
    $products_per_page = 8;
    $total_pages = ceil($total_products / $products_per_page);

    if ($current_page > $total_pages) {
        header("Location: ./?pg=" . $total_pages);
    }


    echo "<pre>";
    echo "Total Products: ";
    var_dump($total_products);
    echo "\nTotal Pages: ";
    var_dump($total_pages);
    echo "\nCurrent Page: ";
    var_dump($current_page);
    exit;




    $products = get_products_all();
