What are the potential security risks associated with using file_get_html in PHP?

Using file_get_html in PHP can pose security risks such as exposing sensitive information, allowing for remote code execution, and potential injection attacks. To mitigate these risks, it is recommended to use a more secure alternative like cURL or consider implementing proper input validation and sanitization. 

// Using cURL instead of file_get_html to fetch a webpage securely
$url = 'https://example.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

// Process the fetched webpage content
$html = new simple_html_dom();
$html->load($result);
