What are the potential security risks associated with scraping and manipulating HTML content in PHP scripts?

Potential security risks associated with scraping and manipulating HTML content in PHP scripts include injection attacks, cross-site scripting (XSS) vulnerabilities, and data leakage. To mitigate these risks, it is important to sanitize user input, validate data before processing it, and avoid executing user-provided scripts or code. 

// Example of sanitizing user input before using it in an HTML manipulation script
$userInput = $_POST['user_input'];
$cleanUserInput = htmlspecialchars($userInput, ENT_QUOTES, 'UTF-8');
echo $cleanUserInput;
