What potential issues can arise when using fsockopen() to call a PHP file?

One potential issue when using fsockopen() to call a PHP file is that it may not handle SSL connections properly, leading to security vulnerabilities. To solve this issue, you can use the stream_socket_client() function instead, which provides better support for SSL connections. 

$host = 'example.com';
$port = 443;
$timeout = 30;
$context = stream_context_create(['ssl' => ['verify_peer' => false, 'verify_peer_name' => false]]);
$socket = stream_socket_client("ssl://$host:$port", $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, $context);

if (!$socket) {
    echo "Failed to connect: $errstr ($errno)";
} else {
    // Connection successful, proceed with sending/receiving data
    fclose($socket);
}
