What are the potential drawbacks of using frames in PHP for updating content?

One potential drawback of using frames in PHP for updating content is that it can lead to issues with search engine optimization (SEO) as search engines may not be able to properly index the content within frames. To solve this issue, it is recommended to use AJAX to dynamically update content on the page without the need for frames. 

// Example of using AJAX to update content dynamically without frames

<script>
function updateContent() {
    var xhttp = new XMLHttpRequest();
    xhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            document.getElementById("content").innerHTML = this.responseText;
        }
    };
    xhttp.open("GET", "update_content.php", true);
    xhttp.send();
}
</script>

<div id="content">
    <!-- Content will be updated dynamically here -->
</div>

<button onclick="updateContent()">Update Content</button>
