PHP, если заявление с пунктами либо еще

Question

Я получаю следующее сообщение об ошибке из PHP

от компилятора

Parse error: syntax error, unexpected 'else' (T_ELSE) in C:\wamp\www\project alpha\functions.php 

Я прокомментировал заявление еще с- //ERROR ON THIS ELSE STATEMENT в коде ниже. Но я не могу понять, почему он терпит неудачу.

У вас возникла проблема с кодом?

function login($email, $password, $mysqli) { 
    // Using prepared statements means that SQL injection is not possible. 
    if ($stmt = $mysqli - > prepare("SELECT carer_id, username, password 
    FROM carers 
    WHERE email = ? 
    LIMIT 1")) { 
    $stmt - > bind_param('s', $email); // Bind "$email" to parameter.

    $stmt - > store_result(); 

    // get variables from db result. 
    $stmt - > bind_result($user_id, $username, $db_password);
