What are the best practices for handling composite URL codes and embedding them in iframes in PHP?

Handling composite URL codes in iframes in PHP involves properly encoding the URL to ensure it is safe for embedding. One common approach is to use the `urlencode()` function to encode the URL before embedding it in the iframe src attribute. This helps prevent any potential security risks or errors that may arise from improperly formatted URLs. 

<?php
// Example composite URL code
$compositeUrl = "https://example.com/page.php?param1=value1&param2=value2";

// Encode the composite URL
$encodedUrl = urlencode($compositeUrl);
?>

<iframe src="<?php echo $encodedUrl; ?>"></iframe>
