How can PHP variables be dynamically changed and updated based on user interaction?

To dynamically change and update PHP variables based on user interaction, you can use AJAX to send requests to the server and update the variables accordingly. This allows for real-time updates without the need to refresh the page. 

<?php
// Initialize the variable
$dynamicVariable = "Initial Value";

// Check if the variable needs to be updated
if(isset($_POST['newVariableValue'])){
    $dynamicVariable = $_POST['newVariableValue'];
}

// Output the variable
echo $dynamicVariable;
?>
