What is the purpose of validating HTML in PHP development, and how can it be done effectively?

Validating HTML in PHP development ensures that the code follows the correct syntax and structure, which helps in creating a consistent and error-free website. This can be done effectively by using PHP libraries like HTML Purifier or by utilizing online validation tools. 

// Example using HTML Purifier library to validate HTML

$config = HTMLPurifier_Config::createDefault();
$purifier = new HTMLPurifier($config);
$cleanHtml = $purifier->purify($dirtyHtml);
