    I believe next code snippet will help you. First of all you have saw an error because you don’t ensure element with that index exists. Secondary, I have refactore the code to make it easily to read and extend, please take a look

    <?php

function message()
{
    $messageMap = [
        "signup_err_password" => "lease enter the password in correct form !!!",
        "loginErr"            => "The email or the password is incorrect !!!",
        "usedEmail"           => "This email is already used !!!",
        "wentWrong"           => "Something went wrong !!!",
        "empty_err"           => "please don't leave anything empty !!!",
        "signup_err_email"    => "please enter the email in the correct form !!!"
    ];
    
    if (array_key_exists('message', $_SESSION)) {
        if(array_key_exists((string)$_SESSION['message'], $messageMap)) {
            printf("<div class='alert alert-danger' role='alert'>%s</div>", $messageMap[$_SESSION['message']]);
            unset($_SESSION['message']);
        }
    }
}

    there are no errors in the code you provided. most likely you copied it from the wrong file. Or maybe you didn’t have this check before

    if (isset($_SESSION['message']))

    then you added it and forgot to upload it to your server.
