Example 2: how to pass value from one php page to another using session

//Thanks for the answers above. Here's how I did it, I hope it helps those who follow. I'm looking to pass a registration number from one page to another, hence regName and regValue:

//Create your first page, call it set_reg.php:

<?php

session_start();

$_SESSION['regName'] = $regValue;

?>

<form method="get" action="get_reg.php">
    <input type="text" name="regName" value="">
    <input type="submit">
</form>
  
//Create your second page, call it get_reg.php:

<?php

session_start();

$regValue = $_GET['regName'];

echo "Your registration is: ".$regValue.".";

?>

<p><a href="set_reg.php">Back to set_reg.php</a>
