What are some alternative methods to iFrames in PHP for loading content within a specific page area?

iFrames can sometimes cause issues with responsiveness and SEO, so it's beneficial to explore alternative methods for loading content within a specific page area in PHP. One common alternative is to use AJAX to dynamically load content without refreshing the entire page. This can be achieved by making an asynchronous request to a PHP script that retrieves the content and then updating the page with the new data. 

<!-- HTML -->
<div id="content"></div>

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

```php
// load_content.php
<?php
// Retrieve content from database or external source
$content = "This is the dynamically loaded content.";

echo $content;
?>
