How secure is it to set "allow_url_fopen = On" in the php.ini file, especially when using Facebook connect?

Setting "allow_url_fopen = On" in the php.ini file can pose a security risk as it allows PHP scripts to open remote files, which can potentially lead to remote code execution or other vulnerabilities. It is generally recommended to keep this setting off for security purposes. When using Facebook connect, it is better to use cURL or other secure methods to interact with remote resources. 

// Example code using cURL to interact with Facebook API instead of allow_url_fopen
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/user_id');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

// Process the response from Facebook API
