Проблема с проверкой хэша пароля пользователя при авторизации на PHP

Question

при проверке пароля зарегистрированного пользователя возникает ошибка-пароль неверный, хотя ввожу его корректно. Просьба помочь с кодом проверки хэша пароля, думаю ошибка в нем, но не могу найти где именно. Код файла логина и файла регистрации прилагаю.

Регистрация
<?php
require_once "config.php";
require_once "session.php";
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['submit'])) {
$fullname = trim($_POST['name']);
$email = trim($_POST['email']);
$password = trim($_POST['password']);
$confirm_password = trim($_POST[&quot;confirm_password&quot;]);
$password_hash = password_hash($password, PASSWORD_BCRYPT);

if($query = $db-&gt;prepare(&quot;SELECT * FROM users WHERE email = ?&quot;)) {
    $error = '';
    // Bind parameters (s = string, i = int, b = blob, etc), in our case the username is a string so we use &quot;s&quot;
$query-&gt;bind_param('s', $email);
$query-&gt;execute();
// Store the result so we can check if the account exists in the database.
$query-&gt;store_result();
    if ($query-&gt;num_rows &gt; 0) {
        $error .= '&lt;p class=&quot;error&quot;&gt;The email address is already registered!&lt;/p&gt;';
    } else {
        // Validate password
        if (strlen($password ) &lt; 6) {
            $error .= '&lt;p class=&quot;error&quot;&gt;Password must have atleast 6 characters.&lt;/p&gt;';
        }
