What is the purpose of using the jQuery .load method to pass parameters to a PHP script?

When using the jQuery .load method to pass parameters to a PHP script, the purpose is to dynamically load content from the server and pass data along with the request. This allows for the PHP script to process the parameters and return specific content based on the data sent from the client-side. 

<?php
// Retrieve the parameter passed from the jQuery .load method
$param = $_GET['param'];

// Process the parameter and return specific content
if ($param == 'example') {
    echo "This is an example content.";
} else {
    echo "Invalid parameter.";
}
?>
