What are the potential pitfalls of using include() and fopen() functions when accessing data from a remote server in PHP?

Using include() and fopen() functions to access data from a remote server can pose security risks, as it can allow for remote code execution and expose sensitive information. To mitigate these risks, it is recommended to use cURL functions in PHP, which provide more control over the request and response handling. 

// Using cURL to access data from a remote server
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/data.txt');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

// Process the response data
echo $response;
