What are some alternative approaches to using iframes in PHP for displaying external content that may be more reliable or efficient?

Using iframes in PHP to display external content can sometimes be unreliable or inefficient due to security concerns and potential performance issues. One alternative approach is to use PHP's cURL library to fetch the external content and then display it directly in the page. This method allows for more control over the content being fetched and displayed, as well as better performance. 

<?php
$url = 'https://example.com/external-content';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

echo $output;
?>
