What are the advantages and disadvantages of using AJAX in PHP for dynamically loading content on a webpage?

Using AJAX in PHP for dynamically loading content on a webpage can provide a more seamless user experience by allowing parts of the page to be updated without refreshing the entire page. This can lead to faster load times and a more interactive interface. However, it can also increase the complexity of the code and require additional server-side processing, which may impact performance.

                    url: 'load_content.php',
                    success: function(data){
                        $('#content').html(data);
                    }
