Are there alternative methods to using iframes in PHP to prevent security breaches and errors?

Using iframes in PHP can potentially lead to security breaches and errors, as they can allow for malicious content to be displayed on a webpage. One alternative method to prevent these issues is to use PHP's built-in functions for handling external content, such as file_get_contents or cURL, to fetch and display content from external sources in a more controlled manner.

<?php

$url = 'https://example.com';
$content = file_get_contents($url);

echo $content;

?>
