What security considerations should be taken into account when accessing remote files using PHP fopen function, especially over HTTPS?

When accessing remote files using PHP's fopen function over HTTPS, it is important to ensure that the connection is secure to prevent potential security risks such as man-in-the-middle attacks. To enhance security, you should verify the SSL certificate of the remote server to ensure its authenticity before establishing the connection. 

$context = stream_context_create([
    'ssl' => [
        'verify_peer' => true,
        'verify_peer_name' => true,
        'allow_self_signed' => false
    ]
]);

$file = fopen('https://example.com/file.txt', 'r', false, $context);

if ($file) {
    // File handling code
    fclose($file);
} else {
    // Handle connection error
}
