What are some considerations to keep in mind when dealing with special characters in HTML content when using PHP for data extraction?

Special characters in HTML content can cause issues when using PHP for data extraction, as they can be encoded in various ways (such as HTML entities or UTF-8 characters). To properly handle special characters, you should use PHP's htmlspecialchars_decode() function to convert HTML entities back to their original characters before extracting data. 

// Example code snippet to extract data from HTML content with special characters
$htmlContent = '<p>This is an example with special characters: & < ></p>';
$decodedContent = htmlspecialchars_decode($htmlContent, ENT_QUOTES);
echo strip_tags($decodedContent); // Extract data without HTML tags
