PHP哈希问题

我正在注册/登录，无法获得匹配的哈希密码

if(isset($_POST["pass"])) {
  $pass = $_POST["pass"];
  $options = array('cost' => 11);
  $pass = password_hash("$pass", PASSWORD_BCRYPT, $options)."\n";    
} 

$sql2 = $db->prepare('INSERT INTO Registrace (Email, Password, Nick) VALUES (:email, :password, :nick)');
$sql2->execute(array(':email' => $email,':password' => $pass, ':nick' => $nick));

已在数据库中输入哈希密码

现在，如何使登录中的密码与数据库中的密码匹配

if(isset($_POST["pass"])) {
  ? ? ? ? ?     
}



$sql = $db->prepare("SELECT Nick,Password FROM registrace WHERE Nick=:nick AND Password=:password");
    $sql->bindParam(':nick', $_POST['lognick']);
    $sql->bindParam(':password', $pass);
    $sql->execute();

    if($row = $sql->fetch()){
        $_SESSION['lognick'] = $row['lognick'];
        $_SESSION['lognick'] = $_POST["lognick"];
        $_SESSION['time'] = time();
        header("Location: Logged.php");
}
else {
  $_SESSION['error'] .= "Pass and Nick don't match.  ";
  header("Location: Login.php");   
}

知道怎么做吗？

查找密码哈希，然后按如下方式检查输入的密码：

if (password_verify($_POST['pass'], $row['Password'])) {
    // Logged in
} else {
    // Wrong password
}

查找密码哈希，然后检查输入的密码，如下所示：

if (password_verify($_POST['pass'], $row['Password'])) {
    // Logged in

您需要做的是在数据库中找到用户名并检索哈希，然后将其传递给
