Avoiding DOMDocument Warning: Unexpected Entity in HTML Parse

When utilizing DOMDocument to load HTML, you may encounter a warning: "htmlParseEntityRef: expecting ';' in Entity." This warning indicates a discrepancy in the HTML entity syntax. To resolve this issue and prevent the warning, it's recommended to enable internal error handling using libxml_use_internal_errors(true) before loading the HTML.

Example:

// create new DOMDocument
$document = new \DOMDocument('1.0', 'UTF-8');

// set error level
$internalErrors = libxml_use_internal_errors(true);

// load HTML
$document->loadHTML($html);

// Restore error level
libxml_use_internal_errors($internalErrors);

By enabling internal error handling, any errors encountered during the HTML parsing will be stored internally instead of being displayed as warnings. This allows for a cleaner and more efficient error-handling mechanism.
