Phpassを使用して登録ユーザーのパスワードをハッシュし、データベースに保存しましたが、現在、送信されたユーザー名とパスワードを確認し、ユーザー名がデータベースに存在することを確認し、ハッシュされたパスワードを指定されたものと照合する方法でログインに行き詰まっています。
どんな助けでも大歓迎です!!! ありがとうございました!
これは私のコードです:
<?php
// Inialize session
session_start();
// Include database connection settings
include('config.inc');
require("PasswordHash.php");
$hasher = new PasswordHash(8, false);
$username = $_POST['username'];
$password = $_POST['password'];
// Passwords should never be longer than 72 characters to prevent DoS attacks
if (strlen($password) > 72) { die("Password must be 72 characters or less"); }
$query = "SELECT * FROM user WHERE username = '$username'";
$query = mysql_query($query);
$numrows = mysql_num_rows($query);
if ($numrows = 1) {
$res = mysql_query("SELECT password FROM user WHERE username = '$username'");
$row = mysql_fetch_array($res);
$hash = $row['password'];
$password = $_POST['password'];
if ($hasher->CheckPassword($password, $hash)) { //$hash is the hash retrieved from the DB
$what = 'Authentication succeeded';
} else {
$what = 'Authentication failed';
}
} else {
echo "No Such User";
include 'login.php';
exit();
}
echo "$what\n";
echo "<br />";
echo "$hash";
?>
これは、他の人の利益のための私の作業コードです:

$query = "SELECT * FROM user WHERE username = '$username'";
$query = mysql_query($query);
$numrows = mysql_num_rows($query);
