What are the potential pitfalls of using ini_set('allow_url_fopen', 'On') to bypass URL file-access restrictions?

Using ini_set('allow_url_fopen', 'On') to bypass URL file-access restrictions can pose security risks by allowing remote file inclusion attacks and exposing sensitive information. It is recommended to avoid using this method and instead use cURL or other secure methods for accessing remote files.

// Use cURL to securely access remote files
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
