How can PHP parameters be properly passed in a link within an iframe?

When passing PHP parameters in a link within an iframe, you need to make sure that the parameters are properly encoded to prevent any issues with special characters. One way to achieve this is by using the `urlencode()` function in PHP to encode the parameters before appending them to the link in the iframe. 

<?php
$param1 = 'value1';
$param2 = 'value2';

$encoded_param1 = urlencode($param1);
$encoded_param2 = urlencode($param2);

echo "<iframe src='example.php?param1=$encoded_param1&param2=$encoded_param2'></iframe>";
?>
