What are some alternative methods to using iFrames for embedding external content in a PHP application?

Using iFrames for embedding external content in a PHP application can sometimes lead to security vulnerabilities and performance issues. An alternative method is to use PHP's built-in functions like file_get_contents() to fetch external content and then display it within your application. This method gives you more control over the content being displayed and can help improve the security and performance of your application.

<?php
// Fetch external content using file_get_contents()
$externalContent = file_get_contents('https://www.example.com');

// Display the external content within your application
echo $externalContent;
?>
