using @ symbol with ftp stream in DirectoryIterator

I'm using DirectoryIterator class to list ftp content: $a = new DirectoryIterator('ftp://user:password@host');

If there is an at "@" character in login, i get an error: failed to op开发者_运维百科en dir: operation failed

How i can escape @ symbol in login?

I try: %40, + \@

RFC1738 mandates the special characters like @ should be urlencoded in the ftp:// scheme. So using %40 in place of the @ in a password fragement would be correct.

But you just wanted the user:password@ prefix before the hostname. Those don't need escaping. And it's already natively supported by the ftp fopen url wrapper:

$d = opendir("ftp://anonymous:nopwd@ftp.kernel.org/pub/");
print readdir($d);

Above ftp:// url works for me with DirectoryIterator too, but gives some obscure warning and different results. So I would test with the native functions first.

I am not that sure you can use DirectoryIterator as FTP client
