PHP：会话在实时服务器中无法正常工作？
[英]PHP: Session not working correctly in live server?
问题描述
My sessions are working correctly in my localhost. 
我的会话在本地主机中正常运行。 But when I use it in live server it needs to be logged out first for login. 但是，当我在实时服务器中使用它时，需要先注销它才能登录。 For example, when I have to login I will first log out then log in otherwise it shows a blank page. 例如，当我必须登录时，我将先注销然后登录，否则它将显示空白页面。 I don't know why this is happening. 我不知道为什么会这样。
This is my Login page 这是我的登录页面
<?php
session_start();
if(isset($_SESSION['user_id']) && $_SESSION['login']=="true") {
header("location:userOwnProfile.php");
exit();
}
else
{
?>

session_destroy();

I want to know why this is happening in live server. 我想知道为什么这在实时服务器中发生。 Why I need to log out first to get myself logged in. 为什么我需要先注销才能登录。

Your userOwnProfile.php script sending output before sending header. 您的userOwnProfile.php脚本在发送标头之前发送输出。 There are some spaces before <?php tag. <?php标记之前有一些空格。 Remove those spaces. 删除那些空格。 Hope this will help 希望这会有所帮助
