What could be the potential reasons for the file_get_contents() function working offline but not online on a web server?

The potential reasons for the file_get_contents() function working offline but not online on a web server could include network connectivity issues, server configuration restrictions, or firewall settings blocking outgoing requests. To solve this issue, you can try using cURL to fetch the content instead, as it provides more flexibility and control over HTTP requests. 

// Using cURL to fetch content instead of file_get_contents
$url = 'https://example.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

if($response === false){
    echo 'Error: ' . curl_error($ch);
} else {
    echo $response;
}

curl_close($ch);
