Are there any best practices for securely transferring data between servers using file() in PHP?

When transferring data between servers using file() in PHP, it is important to ensure the data is transferred securely to prevent unauthorized access or interception. One best practice is to use HTTPS to encrypt the data during transfer. This can be achieved by specifying 'https://' in the URL when using file() to fetch data from a remote server. 

// Example of securely transferring data between servers using file() in PHP
$url = 'https://www.example.com/data.txt';
$data = file($url);

if ($data === false) {
    echo "Failed to fetch data.";
} else {
    // Process the fetched data
    foreach ($data as $line) {
        echo $line;
    }
}
