session_start() problem

[veeraa2003]

Hello everybody........


I used session function to start it in my PHP page . I got some error , Please give some ideas to rectify it.

I provided both of sample of my code and error message. Please go through it .
[code]
<?php
ini_set('mbstring.internal_encoding', 'UTF-8');
ini_set('mbstring.http_output', 'UTF-8');
ini_set('mbstring.detect_order', 'UTF-8');
ini_set('mbstring.substitute_character', '12307');

// When did we start?
define('START_TIME', microtime(true));
   
$sys_path = str_replace('/system', '', dirname(__FILE__));

// Setup paths
define('DS', DIRECTORY_SEPARATOR);
define('ROOT', $sys_path);
define('APP', ROOT . DS . 'app');
define('APP_MODELS', APP . DS . 'models');
define('APP_CONTROLLERS', APP . DS . 'controllers');
define('APP_VIEWS', APP . DS . 'views');
define('SYS', ROOT . DS . 'system');
define('SYSDRIVERS', ROOT . DS . 'system' . DS . 'drivers');
define('LIB', ROOT . DS . 'lib');
define('CONFIG', ROOT . DS . 'config');

define('SESSION_USER', 'user');
echo ROOT;
session_save_path(ROOT . DS . 'tmp' . DS . 'sessions');
session_name(SESSION_USER);
session_start();
?>
[/code]


And the errors are here........

the first error is your problem. the others are a knock-on effect. Is it a server you have full access to? If so, you'll need to make sure the permissions on the sessions directory are set up correctly to allow the session files to be created.

is there any reason why you need to set up a custom session save path? if not, remove/comment out this line:

[code]
<?php
session_save_path(ROOT . DS . 'tmp' . DS . 'sessions');
?>
[/code]

and try again
