How can developers ensure that HTML code stored in a database is properly rendered and displayed on a webpage using PHP?

When storing HTML code in a database, developers need to ensure that the code is properly escaped to prevent any potential security vulnerabilities such as cross-site scripting attacks. To render and display the HTML code on a webpage using PHP, developers can use the htmlspecialchars function to escape the HTML characters before outputting the content. 

<?php
// Retrieve HTML code from the database
$htmlCode = "<p>This is some <strong>HTML</strong> code</p>";

// Escape HTML characters before outputting
echo htmlspecialchars($htmlCode);
?>
