What are the potential pitfalls or bugs that may arise when parsing HTML content using PHP?

One potential pitfall when parsing HTML content using PHP is that the HTML structure may not be well-formed, leading to parsing errors. To solve this issue, you can use the `libxml_use_internal_errors()` function to suppress parsing errors and continue parsing the HTML content. 

// Suppress parsing errors
libxml_use_internal_errors(true);

// Parse the HTML content
$doc = new DOMDocument();
$doc->loadHTML($htmlContent);

// Clear any parsing errors
libxml_clear_errors();
