這是顯示輸入數據的位置。目前，它只是顯示電子郵件，它不會顯示電話，城市和county.I想顯示所有這些信息爲用戶在其中輸入數據的特定用戶如何從PHP中的不同頁面檢索會話信息？
<?php
session_start();
if(!($_SESSION['email'])){
header("location: login.php");
}
?>
<html>
<head>
<title>Login Page</title>
</head>
<style type='text/css'>
body{
background:url('wellcome.png');
}
</style>
<body><b>Welcome you have succesfully logged into your account</b>
<p></p>
<font color='red' size='5'><?php echo $_SESSION['email'];?>
</font>
<font color='red' size='5'><?php echo $_SESSION['name'];?>
<font color='red' size='5'><?php echo $_SESSION['phone'];?>
<font color='red' size='5'><?php echo $_SESSION['city'];?>
<font color='red' size='5'><?php echo $_SESSION['county'];?>
</font>
<h1 align='right' style='margin-right:50px; margin-top:50px'>

這是我的登錄頁面。這是用戶輸入他們的電子郵件和密碼登錄的地方。當用戶登錄進入歡迎頁面時，我想讓他們看到他們的個人信息，例如姓名，電話，城市和縣。

我沒有看到你設置了會話的位置 – Mihai
**這是你的意思嗎？這是從我的登錄頁面** if（isset（$ _ POST ['login']））{ \t $ password = $ _POST ['pass']; \t $ email = $ _POST ['email']; \t \t \t $ check_email =「select * from user where user_pass ='$ password'AND user_email ='$ email'」; \t \t \t $ run = mysqli_query（$ conn，$ check_email）or die（mysqli_error（$ conn））; \t如果（mysqli_num_rows（$運行）> 0） \t { \t \t $ _SESSION [ '電子郵件'] = $電子郵件; \t \t \t \t \t 回聲\t \t \t 「」; \t \t} \t其他{\t \t \t回聲 「」; \t \t} \t } > – artur
電子郵件均田，你只設置會話這裏'$ _SESSION [「電子郵件」] = $電子郵件;'做所有其他人一樣 – Mihai
