How can one ensure that HTML code is not interpreted while still allowing for code snippets to be posted in a PHP forum?

To ensure that HTML code is not interpreted while still allowing for code snippets to be posted in a PHP forum, you can use the htmlspecialchars function to escape any HTML characters in the code snippets before displaying them on the forum. This will prevent the HTML code from being rendered as actual HTML and instead display it as plain text. 

$codeSnippet = "<html><body><h1>Hello, World!</h1></body></html>";
echo htmlspecialchars($codeSnippet);
