如何使用PHP从一个页面继续到另一个页面的会话 [英] How do I continue a session from one page to another with PHP

问题描述

好的，我设置了一个会话...但是现在如何在其他页面上使用它呢?

我尝试做

@session_start();

if(isset($_SESSION['$userName'])) {

 echo "Your session is running " . $_SESSION['$userName'];

}

解决方案

如果您的PHP设置是明确的(会话写正常)并且cookie通常发送到浏览器(并保留了)，则您应该可以执行这样的操作

在第一页上:

session_start();
$_SESSION['userName'] = 'Root';

在第二页上:

session_start();
if(isset($_SESSION['userName'])) {
  echo "Your session is running " . $_SESSION['userName'];
}

请注意，在发送任何输出之前，必须先调用session_start()，因此，如果必须在会话_start中使用@，则会隐藏警告.

由于这些是警告，如果给定的示例不起作用，请尝试在调用session_start之前添加它:

error_reporting(E_ALL);

Ok I set up a session... but now how do I make it work on my other pages?

I tried doing

@session_start();

if(isset($_SESSION['$userName'])) {

 echo "Your session is running " . $_SESSION['$userName'];

}

解决方案

If your PHP setup is clear (session writing ok) and cookie normally sent to browser (and preserved), you should be able to do something like this

On first page :

session_start();
$_SESSION['userName'] = 'Root';

On a second page :

session_start();
if(isset($_SESSION['userName'])) {
  echo "Your session is running " . $_SESSION['userName'];
}

Be careful session_start() must be called before any output is sent, so if you had to use the @ for session_start it can hide warnings.

As these are warnings, if given example doesn't work try to add this before calling session_start :

error_reporting(E_ALL);
