Just switched encryption to "crypt" using PHP but now any password works

Question

I am trying to use crypt() in PHP to authenticate users. Here is my code in the login page:

$valid = MemberDB::isValidMember($email_address, $password);
if ($valid == TRUE) {
    $_SESSION['is_valid_member'] = TRUE;
    header("Location: ../welcome/");
    } else {
    $login_message = 'log in';
    include('./view/login.php');
    }

Here is the function that is supposed to bring back True or False:

public static function isValidMember($email_address, $password) {
    $db = Database::getDB();
    $query = "SELECT member_ID, password
              FROM members
              WHERE email_address = :email_address";
    $statement = $db->prepare($query);
    $statement->bindValue(':email_address', $email_address);
    $statement->execute();
    $row = $statement->fetch();
    $statement->closeCursor();
    return $row ? crypt($password, $row['password']) : FALSE;
}

Currently, no matter what password I enter, it lets me in. When I do a var_dump on $valid, it brings back the 98 char string of the encrypted password so I know that $valid does NOT equal TRUE. Please help!

Thanks.

Answer 1

replace

return $row ? crypt($password, $row['password']) : FALSE;

with

return $row ? ($row['password'] == crypt($password, $row['password'])) : FALSE;
