如何安全地存儲用戶的密碼？這比平淡有多安全？MD5？我剛開始調查密碼安全問題。我對PHP非常陌生。$salt = 'csdnfgksdgojnmfnb';$password = md5($salt.$_POST['password']);$result = mysql_query("SELECT id FROM users
WHERE username = '".mysql_real_escape_string($_POST['username'])."'
AND password = '$password'");if (mysql_num_rows($result) < 1) {
/* Access denied */
echo "The username or password you entered is incorrect.";} else {
$_SESSION['id'] = mysql_result($result, 0, 'id');
#header("Location: ./");
echo "Hello $_SESSION[id]!";}
