Question

I am setting a session variable inside a function studNameDetails1()
while I am trying to retrieve it in a function ViewMark(). These are my two functions but there is no result:

function studNameDetails1()
{
     $_SESSION['ATTsub']=$sub_id = $ID[5];
}
function ViewMark()
{
      echo $_SESSION['ATTsub'];
}

When I echo the value in viewMark(), there is no value.

Answer 1

This is the way to handle sessions.

    <?php // this starts the session 
session_start(); 

    // echo variable from the session, we set this on our other page 
echo "Our color value is ".$_SESSION['color'];  
echo "Our size value is ".$_SESSION['size'];  
echo "Our shape value is ".$_SESSION['shape']; ?>  

All of the values are stored in the $_SESSION array, which we access here. Another way to show this is to simply run this code:

<?php session_start(); Print_r ($_SESSION); ?>
