PHP Session session-variables

如何跨页面使用store和session变量？

发布于 2024-10-27 12:43:34 字数 425 浏览 10 评论 0 原文

当访问一个页面时，我想启动一个会话并存储一个会话变量：

<?php
  session_start(); 
  $_SESSION['myvar']='myvalue';
?>

然后从另一个页面，我想检查该会话变量是否已存储：

<?php
    session_start();
    echo("1");
    if(isset($_SESSION['myvar']))
    {
        echo("2");
       if($_SESSION['myvar'] == 'myvalue')
       {
           echo("3");
           exit;
       }
    }
    ?>

此代码对我不起作用。

原文

When one page is accessed, I would like to start a session and store a session variable:

<?php
  session_start(); 
  $_SESSION['myvar']='myvalue';
?>

Then from another page, I would like to check if that session variable has been stored:

<?php
    session_start();
    echo("1");
    if(isset($_SESSION['myvar']))
    {
        echo("2");
       if($_SESSION['myvar'] == 'myvalue')
       {
           echo("3");
           exit;
       }
    }
    ?>

This code does not work for me.

逐步进行会话

在一切之前定义会话，在此之前不应有任何输出，无输出

<前><代码>
在页面内设置会话，然后您就可以访问该页面。例如，这是第 1.php 页

<前><代码>[电子邮件受保护]';
？>
在2.php中使用和获取会话

<前><代码>

注意：注释没有输出。< /em>

Sessions Step By Step

Defining session before everything, No output should be before that, NO OUTPUT
```
<?php
session_start();
?>
```

Set your session inside a page and then you have access in that page. For example this is page 1.php

<?php
   //This is page 1 and then we will use session that defined from this page:
    session_start();
    $_SESSION['email']='[email protected]';
?>

Using and Getting session in 2.php

 <?php

//In this page I am going to use session:

  session_start();
  if($_SESSION['email']){
  echo 'Your Email Is Here!  :) ';
  }
 ?>

NOTE: Comments don't have output.

你要做的就是写 --- session_start(); ----- 在两页上..

<!-- first page -->
<?php
  session_start(); 
  $_SESSION['myvar'] = 'hello';
?>

<!-- second page -->
<?php
    session_start();
    echo $_SESSION['myvar']; // it will print hello 

?>

All you want to do is write --- session_start(); ----- on both pages..

<!-- first page -->
<?php
  session_start(); 
  $_SESSION['myvar'] = 'hello';
?>

<!-- second page -->
<?php
    session_start();
    echo $_SESSION['myvar']; // it will print hello 

?>

从对此问题的评论进行推理，似乎缺乏调整后的 session.save_path 会导致 PHP 会话处理程序出现这种错误行为。只需指定一个存在且可由 PHP 读取和写入的目录（在文档根目录之外）即可解决此问题。

如果第二个页面没有对会话 cookie 的共享访问权限，您需要使用 session_set_cookie_params：

<?php
session_set_cookie_params( $lifetime, '/shared/path/to/files/' );
session_start();
$_SESSION['myvar']='myvalue';

并且

<?php
session_set_cookie_params( $lifetime, '/shared/path/to/files/' );
session_start();
echo("1");
if(isset($_SESSION['myvar']))
{
    echo("2");
   if($_SESSION['myvar'] == 'myvalue')
   {
       echo("3");
       exit;
   }
}

In the possibility that the second page doesn't have shared access to the session cookie, you'll need to set the session cookie path using session_set_cookie_params:

<?php
session_set_cookie_params( $lifetime, '/shared/path/to/files/' );
session_start();
$_SESSION['myvar']='myvalue';

And

<?php
session_set_cookie_params( $lifetime, '/shared/path/to/files/' );
session_start();
echo("1");
if(isset($_SESSION['myvar']))
{
    echo("2");
   if($_SESSION['myvar'] == 'myvalue')
   {
       echo("3");
       exit;
   }
}

试试这个

第一页

<?php
   session_start();
   $_SESSION['myvar']='myvalue';
?>

第二页

 <?php
   session_start();
   echo $_SESSION['myvar'];
 ?>

Try this

First Page

<?php
   session_start();
   $_SESSION['myvar']='myvalue';
?>

Second page

 <?php
   session_start();
   echo $_SESSION['myvar'];
 ?>

每次启动会话（适用于 PHP 版本 5.2.54）时，session_start() 都会创建一个新的会话 ID。

这是对我有用的修复。

文件1.php

session_id('mySessionID'); //SET id first before calling  session start
session_start();

$name = "Nitin Hurkadli";
$_SESSION['username'] = $name;

文件2.php

session_id('mySessionID'); 
session_start();

$name = $_SESSION['username'];
echo "Hello  " . $name;

Every time you start a session (applies to PHP version 5.2.54), session_start() creates a new session id.

Here is the fix that worked for me.

File1.php

session_id('mySessionID'); //SET id first before calling  session start
session_start();

$name = "Nitin Hurkadli";
$_SESSION['username'] = $name;

File2.php

session_id('mySessionID'); 
session_start();

$name = $_SESSION['username'];
echo "Hello  " . $name;

启动会话：

将以下代码放在文件顶部。

<?php session_start();?>

存储会话变量：

<?php $_SESSION['id']=10; ?>

检查会话变量中是否存储了数据：

<?php if(isset($_SESSION['id']) && !empty(isset($_SESSION['id'])))
echo “Session id “.$_SESSION['id'].” exist”;
else
echo “Session not set “;?>

?>
详细信息请参见http://skillrow.com/sessions-in-php-4/

Starting a Session:

Put below code at the top of file.

<?php session_start();?>

Storing a session variable:

<?php $_SESSION['id']=10; ?>

To Check if data stored in session variable:

<?php if(isset($_SESSION['id']) && !empty(isset($_SESSION['id'])))
echo “Session id “.$_SESSION['id'].” exist”;
else
echo “Session not set “;?>

?>

莫多说 2024-11-03 12:43:35

试试这个：

<!-- first page -->
<?php
  session_start(); 
  session_register('myvar');
  $_SESSION['myvar'] == 'myvalue';
?>

<!-- second page -->
<?php
    session_start();
    echo("1");
    if(session_is_registered('myvar'))
    {
        echo("2");
       if($_SESSION['myvar'] == 'myvalue')
       {
           echo("3");
           exit;
       }
    }
    ?>

Try this:

<!-- first page -->
<?php
  session_start(); 
  session_register('myvar');
  $_SESSION['myvar'] == 'myvalue';
?>

<!-- second page -->
<?php
    session_start();
    echo("1");
    if(session_is_registered('myvar'))
    {
        echo("2");
       if($_SESSION['myvar'] == 'myvalue')
       {
           echo("3");
           exit;
       }
    }
    ?>
