How can PHP be used to open and display HTML files?

To open and display HTML files using PHP, you can use the `file_get_contents()` function to read the contents of the HTML file and then `echo` the contents to display it on the webpage. 

<?php
$html_file = 'example.html'; // specify the HTML file to open

if (file_exists($html_file)) {
    $html_content = file_get_contents($html_file); // read the contents of the HTML file
    echo $html_content; // display the HTML content on the webpage
} else {
    echo 'HTML file not found';
}
?>
