是否可以在一个页面中显示许多会话消息

I would like to display many session messages on one page. The first page is file_upload.php

// Success!
echo "File was uploaded without errors.<br />" . $_SESSION['message'];
echo "File name is '{$file_name}'.<br />" . $_SESSION['message'];
echo "File references an uploaded file. <br />" . $_SESSION['message'];
echo "File was uploaded without errors" . $_SESSION['message'];

Second file is new.php here is $sql = "INSERT INTO products ";(cat_id, prod_name, filename, type, size, filename2, type2, size2, position, visible, content)

$result = insert_products($products);
if($result === true) {

    $new_id = mysqli_insert_id($db);
    $_SESSION['message'] = 'The product has been created.';

    redirect_to(url_for('/staff/pages/show.php?id=' . $new_id));

The third is show.php and here is the function.

<?php echo display_session_message(); ?>

function get_and_clear_session_message() {
    if(isset($_SESSION['message']) && $_SESSION['message'] != '') {
        $msg = $_SESSION['message'];
        unset($_SESSION['message']);
        return $msg;
    }
}

function display_session_message() {
    $msg = get_and_clear_session_message();
    if(!is_blank($msg)) {
        return '<div id="message">' . h($msg) . '</div>';
    }
}

For now, only shows in show.php 'The product has been created' message. Is it possible to display many session messages on one page? I want to add all error message form function file_upload.php.
