Sessions

[TheSeeker]

I am trying to use sessions to store information ( a single row) i pulled out of a database....

for example this is what i do:

             session_start();
$MemberID = $row["MemberID"];
$UserName =$row["UserName"];
session_register("MemberID", "UserName");
Print ("a link to anotherpage.php");

when the link for anotherpage.php is clicked it has this

           session_start();
           print ($UserName);

no session information is stored????

Also i tried this tutorial doesnt work
The first example (page1.php):

<?php

session_start();
$my_session_variable = "some value";
session_register("my_session_variable");

?>

Example 2 (page2.php):

<?php

session_start();
print "Value of 'my_session_variable': $my_session_variable";

?>

is there setting in php that one has to make sure is on for sessions to work....the php.ini file....? or is it the code? anyone know a good step by step phpsesssions tutorial?

I tried this
session_start();
$SESSION['UserName']=$row["UserName"];
$SESSION['MemberID']=$row["MemberID"];

then on the following page i did this

          session_start();
         $UserName =$_SESSION['UserName'];
          print ($UserName);

this does work

question : Why does this work and the code that i tried first doesnt...????

Because the second method is more secure, and your server has globals turned off for security purposes (which is the default).

You can turn globals on if you want to make it easier to write code, but it is not recommended. You will run into other issues as well if you are following one of the gadzillion tutorials around the 'net that assume globals are turned on. All your variables need to be declared and defined explicitly through their respective arrays to write robust, stable code.
