How can a wysiwyg editor handle .html files for editing and saving?

A wysiwyg editor can handle .html files for editing and saving by using a combination of file handling functions in PHP. The editor can load the content of the .html file into a textarea for editing, and then save the edited content back to the file when the user clicks a save button. This can be achieved by reading the content of the file using file_get_contents() and writing the updated content back to the file using file_put_contents(). 

<?php
$file = 'example.html';

if(isset($_POST['save'])){
    $content = $_POST['content'];
    file_put_contents($file, $content);
}

$content = file_get_contents($file);
?>

<form method="post">
    <textarea name="content"><?php echo $content; ?></textarea>
    <input type="submit" name="save" value="Save">
</form>
