How can PHP functions be used to highlight or display the source code of a PHP page?

To highlight or display the source code of a PHP page, you can create a PHP function that reads the contents of the PHP file and then outputs it with syntax highlighting. This can be achieved by using the `highlight_string()` function in PHP to apply syntax highlighting to the code. 

<?php
function displaySourceCode($filePath) {
    $sourceCode = file_get_contents($filePath);
    echo highlight_string($sourceCode, true);
}

// Call the function with the path to the PHP file you want to display
displaySourceCode('path/to/your/file.php');
?>
