How to Resolve the \'DOMDocument::loadHTML(): htmlParseEntityRef: expecting \';\'\' Warning in PHP?

Dissipating the "DOMDocument::loadHTML(): htmlParseEntityRef: expecting ';'" Warning

When attempting to parse HTML content using DOMDocument::loadHTML(), you might stumble upon the following error:

Warning: DOMDocument::loadHTML(): htmlParseEntityRef: expecting ';' in Entity

This vexing warning arises when HTML entities that swap special characters, e.g., "&", are not correctly terminated. To vanquish it, you can employ libxml_use_internal_errors(true):

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

// alter error settings
$internalErrors = libxml_use_internal_errors(true);

// ingest HTML content
$document->loadHTML($html);

// revert error settings
libxml_use_internal_errors($internalErrors);

By setting libxml_use_internal_errors(true), DOMDocument adeptly intercepts the error, preventing its obtrusive display. This approach enables you to gracefully handle the issue and continue parsing your HTML content.
