Please help! I am experiencing this annoying problem with session. My session variable which I made in test1.php cannot pass to test2.php after redirecting. I am completely new to web programming so please lead me to solve this one. I have read different threads with same issue, some say it might be on session.save_path configuration so I went to php.ini file and then it is noted there under sessionsavepath or sessionhandler (im not so sure) that For Windows users: this must be changed to use session’s function. What does that mean?
Here’s my code so far:
test1.php
test2.php
<?php session_start(); echo $_session['sol']; // this gives an error. It says Notice: Undefined variable: _session in C:\xammp\htdocs\test2.php on line 3 ?>Any answer would be appreciated. 
really appreciated your guidance.
