PHP会话处理错误

我在我的send.php文件的顶部有这个：

ob_start();
@session_start();

//some display stuff

$_SESSION['id'] = $id; //$id has a value
header('location: test.php');

以下在我的test.php文件的最上方：

ob_start();
@session_start();

error_reporting(E_ALL);
ini_set('display_errors','1');

print_r($_SESSION);

当数据发送到test.php时,显示如下：

Array ( )

Warning: Unknown: open(/var/lib/php/session/sess_isu2r2bqudeosqvpoo8a67oj02,O_RDWR) failed: Permission denied (13) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0

我试过只使用session_start();但结果是一样的.

首先它与许可有关

打开(/ var / lib / php / session / sess_isu2r2bqudeosqvpoo8a67oj02,O_RDWR)失败：权限被拒绝(13)在未知的第0行

你必须检查文件的权限
改变模式这个/ var / lib / php / session /

第二件事与session.save_path有关

警告：未知：无法写入会话数据(文件).请验证session.save_path的当前设置是否正确(/ var / lib / php / session)在Unknown 0行

在php.ini

[Session]
; Handler used to store/retrieve data.
session.save_handler = files

; Argument passed to save_handler. In the case of files,this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
; As of PHP 4.0.1,you can define the path as:
; session.save_path = "N;/path"
; where N is an integer. Instead of storing all the session files in
; /path,what this will do is use subdirectories N-levels deep,and
; store the session data in those directories. This is useful if you
; or your OS have problems with lots of files in one directory,and is
; a more efficient layout for servers that handle lots of sessions.
; NOTE 1: PHP will not create this directory structure automatically.
; You can use the script in the ext/session dir for that purpose.
; NOTE 2: See the section on garbage collection below if you choose to
; use subdirectories for session storage
session.save_path = /tmp/ //=>HERE YOU HAVE TO MAKE SURE 

; Whether to use cookies.
session.use_cookies = 1
