How can the PHP code be modified to ensure that the ".." is displayed correctly as the back link?
The issue with displaying ".." as the back link in PHP is that it is interpreted as a directory traversal attempt. To ensure that ".." is displayed correctly as the back link, we can use the htmlentities() function to encode the string and prevent any malicious interpretation.
<?php
$link = "<a href='javascript:history.back()'>" . htmlentities('..') . "</a>";
echo $link;
?>
