Are there any specific PHP functions or methods that can be used to display PHP code in its original form before it is converted to HTML?

When displaying PHP code in its original form before it is converted to HTML, you can use the `highlight_string()` function in PHP. This function takes a string of PHP code as input and returns a syntax-highlighted version of the code. By using this function, you can display PHP code in its original form with proper syntax highlighting. 

<?php
$phpCode = '<?php echo "Hello, World!"; ?>';
highlight_string($phpCode);
?>
