How can jQuery be utilized to create pop-up windows in PHP for displaying success or error messages?

To create pop-up windows in PHP for displaying success or error messages, you can utilize jQuery's `alert()` function. This function allows you to display a message in a pop-up dialog box. You can use PHP to generate the necessary JavaScript code that will trigger the alert message based on the success or error conditions in your PHP script. 

<?php
// Check for success or error condition
if ($success) {
    echo '<script type="text/javascript">alert("Success message here");</script>';
} elseif ($error) {
    echo '<script type="text/javascript">alert("Error message here");</script>';
}
?>
