How can PHP developers effectively work with HTML content generated by WYSIWYG editors, considering potential formatting issues?

When working with HTML content generated by WYSIWYG editors, PHP developers can effectively handle potential formatting issues by using PHP libraries like HTML Purifier to sanitize and clean up the HTML code. This ensures that the HTML content is safe and well-formatted before being displayed on the website.

// Include HTML Purifier library
require_once 'path/to/htmlpurifier/library/HTMLPurifier.auto.php';

// Create an instance of HTMLPurifier
$config = HTMLPurifier_Config::createDefault();
$purifier = new HTMLPurifier($config);

// Clean up HTML content generated by WYSIWYG editor
$clean_html = $purifier->purify($html_content);

// Output the sanitized HTML content
echo $clean_html;
