How can PHP be used to dynamically insert text upon a user action?

To dynamically insert text upon a user action in PHP, you can use AJAX to send a request to the server when the user performs the action. The server-side PHP script can then process the request and return the desired text, which can be inserted into the webpage without refreshing the page. 

<?php
if(isset($_POST['user_action'])) {
    // Process the user action and generate the text
    $text = "Text dynamically inserted upon user action";
    
    // Return the text as a response
    echo $text;
}
?>
