How can you directly access a specific tab in Bootstrap 3.x using PHP?

To directly access a specific tab in Bootstrap 3.x using PHP, you can utilize the $_GET superglobal array to retrieve the tab ID from the URL parameters. Then, you can use JavaScript to trigger the tab activation based on the retrieved tab ID.

<?php
$active_tab = isset($_GET['tab']) ? $_GET['tab'] : 'default_tab_id';
?>

<script>
$(document).ready(function(){
    $('#<?php echo $active_tab; ?>').tab('show');
});
</script>
