What are the best practices for loading HTML content in PHP using DOMDocument?

When loading HTML content in PHP using DOMDocument, it is important to follow best practices to ensure the content is parsed correctly. One common issue is that the HTML content may contain special characters or entities that need to be handled properly. To solve this, it is recommended to use the `mb_convert_encoding` function to convert the HTML content to UTF-8 encoding before loading it into DOMDocument. 

// HTML content to be loaded
$htmlContent = "<html><head><title>Example</title></head><body><h1>Hello, World!</h1></body></html>";

// Convert HTML content to UTF-8 encoding
$htmlContent = mb_convert_encoding($htmlContent, 'HTML-ENTITIES', 'UTF-8');

// Create a new DOMDocument object
$dom = new DOMDocument();

// Load the HTML content into the DOMDocument object
$dom->loadHTML($htmlContent);

// Perform operations on the DOMDocument object
// For example, get the title of the HTML document
$title = $dom->getElementsByTagName('title')->item(0)->nodeValue;

echo $title; // Output: Example
