Question

我正在使用$session[login]，但$_SESSION似乎无法在html/php网页的主页上运行。它没有出现任何东西。为什么？任何人都可以帮助我并告诉我为什么？会话名称错了吗？或者需要在里面输入php？

$_SESSION['login'] = true;                  
while($row = mysql_fetch_assoc($result))
{
    $_SESSION['student_id'] = $row['studnet_id'];
    $_SESSION['student_name'] = $row['student_name'];

Answer 1

在使用之前，您必须先启动会话：

session_start();

所以你的代码应该是这样的：

<?php
session_start();
$_SESSION['login'] = true;

（如果你说你使用$session[login]，那么你必须使用它是错误的：$session['login']否则login是一个常数，它不是）

有关详细信息，请参阅：http://php.net/manual/en/function.session-start.php

我的$ _SESSION不能在我的页面上工作么？
