How can session variables be used to store and retrieve dynamic input values in PHP?

Session variables can be used to store dynamic input values in PHP by assigning the input values to session variables when the form is submitted, and then retrieving the values from the session variables on subsequent pages. This allows the input values to persist across different pages of a website until the session is destroyed. 

// Start the session
session_start();

// Store dynamic input value in session variable
$_SESSION['input_value'] = $_POST['input_field'];

// Retrieve dynamic input value from session variable
$input_value = $_SESSION['input_value'];

// Use the retrieved input value
echo "Input value: " . $input_value;
