PHP-从远程服务器获取ftp列表的最佳实践是什么？

Question

What is the best practice for getting the ftp file list from the remote server?

1) Using ftp_connect() function

<?php

// set up connection
$conn = ftp_connect($ftp_server);

// login with username and password
$login = ftp_login($conn, $ftp_user_name, $ftp_user_pass);

// get contents of the current directory
$content = ftp_nlist($conn, ".");

// output content
var_dump($content);
?>

or

2) Using scandir() and then output the file list with print_r()

<?php

$path = "ftp://login:password@ftpserver";

$files = scandir($path);

print_r($files);

?>

Both methods output an array with ftp directories/files.

Answer 1

My opinion is that first one is preferable, why:

1. It clearly states that it is ftp connection, which means that you can use it not only for listing files, but for upload too if you need it later, also you can handle errors properly and provide better error messages or logging
2. Second method relies on allow_url_fopen settings, which is better to disable because of possible security vulnerabilities
