What are common pitfalls to avoid when using Domdocument in PHP for web scraping?

One common pitfall when using DomDocument in PHP for web scraping is not handling errors properly, which can lead to the script crashing unexpectedly. To avoid this, it's important to wrap your DomDocument operations in try-catch blocks to catch any potential errors and handle them gracefully. 

try {
    $doc = new DomDocument();
    $doc->loadHTML($html);
    
    // Your web scraping code here
    
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
