How can individual steps be loaded asynchronously, similar to using Ajax, to create a seamless UI in PHP?

When loading individual steps asynchronously in PHP to create a seamless UI, you can use JavaScript along with PHP to achieve this. By making AJAX requests to the server to load each step separately, you can update the UI without refreshing the entire page. This can help improve the user experience by providing a smoother and more responsive interface.

        $(document).ready(function(){
            loadStep(1);

            function loadStep(step){
                $.ajax({
                    url: 'load_step.php',
                    method: 'POST',
                    data: {step: step},
                    success: function(response){
                        $('#step-container').html(response);
                    }
                });
            }
        });
    </script>
</body>
</html>
```

```php
//load_step.php

<?php
$step = $_POST['step'];

// Load step content based on the step number
if($step == 1){
    echo "Step 1 content here";
} elseif($step == 2){
    echo "Step 2 content here";
} elseif($step == 3){
    echo "Step 3 content here";
}
?>
