How to Suppress \'htmlParseEntityRef: expecting \';\' in Entity\' Warning in PHP?

Resolving "htmlParseEntityRef: expecting ';' in Entity" Warning

When loading HTML content into a DOMDocument, you may encounter the warning "htmlParseEntityRef: expecting ';' in Entity." This error often arises due to malformed HTML entities in the loaded content. To alleviate this warning while ensuring proper entity resolution, follow these steps:

1. Enable Internal Errors: Utilizing the libxml_use_internal_errors(true) function allows internal XML parsing errors to be recorded without abruptly terminating your script. This enables you to handle and process the errors gracefully.
2. Load HTML: Subsequent to activating internal errors, load the HTML content into the DOMDocument as usual using $dom->loadHTML($html).
3. Disable Internal Errors: After loading the HTML, disable internal errors by invoking libxml_use_internal_errors($internalErrors) with the previously stored error level to revert to the default error handling behavior.

By employing this technique, the warning will be suppressed, and the DOMDocument will be correctly populated with the loaded HTML content.

<code class="php">// 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);</code>
