What are common issues when using DOMDocument in PHP to parse HTML code?

One common issue when using DOMDocument in PHP to parse HTML code is that it may not handle poorly formed HTML well, leading to parsing errors. To solve this, you can use the libxml_use_internal_errors function to suppress parsing errors and continue parsing the HTML.

$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($html);
libxml_use_internal_errors(false);
