What are some common pitfalls to avoid when using PHP and AJAX to dynamically update webpage content, such as managing scroll bars for dynamically changing content heights?

One common pitfall when dynamically updating webpage content with PHP and AJAX is not properly managing scroll bars for dynamically changing content heights. To solve this issue, you can use JavaScript to adjust the scroll position of the page after the content has been updated. 

// PHP code to dynamically update webpage content and manage scroll bars

// Process AJAX request to update content
if(isset($_POST['data'])){
    // Update content here
    $newContent = $_POST['data'];

    // Return updated content
    echo $newContent;
    exit;
}
```

```javascript
// JavaScript code to manage scroll bars after content update
// Assuming you are using jQuery for AJAX requests

$.ajax({
    url: 'update_content.php',
    type: 'POST',
    data: { data: newData },
    success: function(response){
        // Update content on the page
        $('#content').html(response);

        // Adjust scroll position to maintain user experience
        var scrollPosition = $(window).scrollTop();
        $(window).scrollTop(scrollPosition);
    }
});
