How do I share a PHP variable between multiple pages?

Question

The idea/goal:

I have a username and password inside a text file on my computer. The form on the index page allows the user to sign in with their us

Answer 1

1. Start a php session on each page right after the opening php tag:

   session_start();

After you determine that the name and password work, and before you do the redirect, add this line:

$_SESSION['name'] = $name;

On any subsequent pages, just echo something like this:

echo "Welcome ".$_SESSION['name'];
