What alternative methods can be used to achieve the same functionality as allow_url_fopen without exposing the server to potential security threats?

The issue with using allow_url_fopen in PHP is that it can potentially expose the server to security threats such as remote code execution and file inclusion attacks. To achieve the same functionality without this risk, you can use cURL or file_get_contents with a stream context that disables URL inclusion. 

// Using cURL to fetch remote content
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);

// Using file_get_contents with stream context
$context = stream_context_create(array(
    'http' => array(
        'follow_location' => false,
        'ignore_errors' => true
    )
));
$output = file_get_contents($url, false, $context);
