How can PHP and JavaScript be effectively combined to create a small window when clicking on a link?

To create a small window when clicking on a link, you can combine PHP and JavaScript by using PHP to dynamically generate the JavaScript code needed for the window to appear. This can be achieved by echoing out JavaScript code within PHP when the link is clicked. The JavaScript code can then be used to display a modal or popup window on the webpage.

<?php
echo '<a href="#" onclick="showWindow()">Click here</a>';
echo '<script>';
echo 'function showWindow() {';
echo '  var modal = document.createElement("div");';
echo '  modal.innerHTML = "This is a small window!";';
echo '  document.body.appendChild(modal);';
echo '}';
echo '</script>';
?>
