目录之间的PHP会话权限问题,对其自己的目录本地执行的全局变量

I have a PHP sessions permission problem. I am using a Linux server running an up-to-date version of PHP. The issue is I set session variables in /var/www/session/here.php and then the session variables load fine in that PHP files and other PHP files the same directory. I am using session_start(); at the beginning of every PHP page.

I am using this to set the sessions:

$_SESSION['example1'] = 983982;

And this to view them:

print_r($_SESSION);

When I access /var/www/training/unit2/lesson4/here.php (a different directory) it does not recognize the variables saved in the global session array, in fact when I make new session variables in that different directory they work fine but the other session variables from before do not show up. When I move the file to the same directory as the other PHP files, the session variables work fine.

I understand this must be some type of PHP global sessions permissions issue. Any ideas what file I have to modify to correct this? When I make new session variables they should be available on every PHP page in any directory. The session vars are getting stored some place with a relative path that is getting broken when they are called from PHP pages in different directories.

Sessions are stored in session.save_path in php.ini. The default location of session vars is /var/lib/php5 which is in a different directory than either of the PHP files I am testing so they should both be able to access it?
