Question

So I create a session on one page and create a new variable called uName and assign a value.
I go to another page and try to echo the value but I get an error:”Undefined variable _SESSION”

here is the code:

The page where I start the session and create the variable uName

<?php 
    session_start();
    $_SESSION['uName'] = "Mike";
?>

The page where I try to echo the variable’s value:

<?php echo "My Name is " . $_SESSION['uName'];?>

There is nothing else in my code except for a shell of a page just html, head, title, body and paragraph tags, all properly nested.

You need to call session_start() again at beginning of the new file, like so:

<?php 
session_start();

echo "My Name is " . $_SESSION['uName'];
