What are the drawbacks of using framesets in web development, and how does it affect retrieving the current URL in PHP?

Framesets in web development have several drawbacks, including making it difficult to retrieve the current URL in PHP. This is because framesets divide a webpage into multiple frames, each with its own URL, making it challenging to determine the main URL of the page. To work around this issue, you can use JavaScript to pass the current URL to a hidden form field, which can then be accessed in PHP. 

<?php
$current_url = isset($_POST['current_url']) ? $_POST['current_url'] : '';

echo "Current URL: " . $current_url;
?>

<form id="urlForm" method="post">
    <input type="hidden" name="current_url" id="current_url" value="">
</form>

<script>
document.getElementById('current_url').value = window.location.href;
document.getElementById('urlForm').submit();
</script>
