我是這個領域的新手，這是我第一次與會話一起工作，這個問題可能看起來很基本，但是如果有人能幫助我，我將不勝感激。目前，我已經使用會話創建了登錄和註銷頁面，並希望顯示已登錄的特定用戶的數據。用戶在登錄後重定向到retailer_login.php，除登錄表單外，整個登錄有4頁和註銷過程。在登錄後使用會話檢索單個用戶數據
retailer_login.php，retailer_session.php，retailer_profile.php，retailer_logout.php
每一頁都工作正常，但是我能夠顯示來自數據庫的用戶只有單一數據列，但我想顯示整個存儲有關該特定用戶的信息。

} else {
// Define $email and $password
$email = $_POST['email'];
$password = $_POST['password'];
// To protect MySQL injection for Security purpose

$query = mysql_query("select * from retailerregister where password='$password' AND email='$email'", $connection);
$rows = mysql_num_rows($query);
if ($rows != 1)
throw new Exception("email or Password is invalid");

現在我只能以個人資料頁上顯示的電子郵件使用$login_session。誰能告訴我如何通過會話顯示已登錄的用戶的retailer_profile頁面上的其他數據
