Are there specific PHP libraries or frameworks that can help in sanitizing user input to prevent HTML injection?

HTML injection can be prevented by sanitizing user input to remove any potentially harmful HTML tags. PHP libraries like HTMLPurifier or frameworks like Laravel provide functions and methods to sanitize input and prevent HTML injection. By using these tools, you can ensure that user input is safe and does not pose a security risk to your application. 

// Using HTMLPurifier to sanitize user input
require_once 'path/to/htmlpurifier/library/HTMLPurifier.auto.php';

$config = HTMLPurifier_Config::createDefault();
$purifier = new HTMLPurifier($config);

$dirty_html = '<script>alert("XSS attack!")</script>';
$clean_html = $purifier->purify($dirty_html);

echo $clean_html;
