What is the best practice for passing a link as text in PHP, especially when dealing with form data?

When passing a link as text in PHP, especially when dealing with form data, it is important to properly encode the link to prevent any potential security vulnerabilities or data corruption. One common method is to use the `htmlspecialchars()` function to escape special characters in the link before outputting it in the HTML document. This ensures that the link is displayed correctly and safely. 

$link = "https://www.example.com/page.php?id=123";
$encodedLink = htmlspecialchars($link);
echo "<a href='$encodedLink'>$encodedLink</a>";
