In what situations is it recommended to use JavaScript to retrieve the current URL instead of relying on PHP?

In situations where the URL needs to be dynamically updated without refreshing the page, it is recommended to use JavaScript to retrieve the current URL. This is especially useful for single-page applications or when interacting with APIs that require the current URL. By using JavaScript, the URL can be easily accessed and manipulated without the need for server-side processing. 

// PHP code snippet to retrieve the current URL using JavaScript
echo '<script>';
echo 'var currentUrl = window.location.href;';
echo 'console.log("Current URL: " + currentUrl);';
echo '</script>';
