ftp_site

(PHP 4, PHP 5, PHP 7, PHP 8)

ftp_site — SITEコマンドをサーバーに送信する

説明

ftp_site(FTP\Connection $ftp, string $command): bool

ftp_site() は、指定された SITE コマンドを FTP サーバーに送信します。

SITE コマンドの規格は統一されていないため、サーバーにより仕様が異なります．ファイルのパーミッションやグループメンバーの設定のような処理を行う際には有用です。

パラメータ

ftp: FTP\Connection クラスのインスタンス
command: SITE コマンド。このパラメータはエスケープされないので、スペースやその他の文字を含むファイル名は問題を引き起こす可能性があることに注意してください。

戻り値

成功した場合に true を、失敗した場合に false を返します。

変更履歴

バージョン	説明
8.1.0	引数 `ftp` は、FTP\Connection のインスタンスを期待するようになりました。これより前のバージョンでは、リソースを期待していました。

例

例1 SITE コマンドを FTP サーバーに送信する

<?php
// FTP サーバーに接続する
$ftp = ftp_connect('ftp.example.com');
if (!$ftp) die('Unable to connect to ftp.example.com');

// "user" として、パスワード "pass" でログインする
if (!ftp_login($ftp, 'user', 'pass')) die('Error logging into ftp.example.com');


// FTP サーバーに "SITE CHMOD 0600 /home/user/privatefile" コマンドを発行する
if (ftp_site($ftp, 'CHMOD 0600 /home/user/privatefile')) {
   echo "Command executed successfully.\n";
} else {
   die('Command failed.');
}
?>

To send a SITE command and get the result, you can try this:



<?php

function ftpsite($conn, $cmd) {

    return ftp_raw($conn, "SITE $cmd");

}

?>

Hya, 
  Recently I had to work with FTP over PHP, since I didn't found any help about this topic I decided to post this here. If you need to chmod one file, I tested this on the ftp server using a ftp client and after I knew that the ftp server supported chmod I used the following commands:
$upload = ftp_put($conn_id, "/home/to/public_html/index.php", $source_file, FTP_ASCII);
$ch=@ftp_site($conn_id,"chmod 755 /home/to/public_html/index.php");

Hope this help!

site commands are extra-functionality provided by some ftp servers, and depend on the server : 

e.g. trying "ftp> site help" (with an interactive ftp client) on a proftp server would give :

 

214-The following SITE extensions are recognized:

 RATIO -- show all ratios in effect

 The following SITE commands are recognized (* =>'s unimplemented).

 HELP    CHMOD

214 Direct comments to admin@ftp.blahblah.fr



while with wu-ftpd on can typically get :



214-The following SITE commands are recognized (* =>'s unimplemented).

   UMASK           GROUP           INDEX           GROUPS

   IDLE            GPASS           EXEC            CHECKMETHOD

   CHMOD           NEWER           ALIAS           CHECKSUM

   HELP            MINFO           CDPATH                   

214 blabla



Unfortunately, ftp_site only returns true or false. It would be nice to have a way to get the server's reply in full : ftp_site('help') return 1, which pretty much useless.



Hope that helps,



Ivan

Use ftp_raw() (PHP 5+) instead of ftp_site() if you need the results of the remote command.

I'd like to follow up with Ivan's observation there. Unless I am missing the obvious, which is entirely possible of course, this command is quite useless unless it returns the data from the SITE <foo> request.

Besides the obvious SITE HELP command, another one that would require catching the feedback would be the SITE LOCATE | SITE SEARCH commands. I completely recognize that SITE <foo> commands are indeed insanely proprietary, but the fact still remains that changing this to return the results, or at least having the option to do so (such as exec() and the like) would be vastly preferred to the current method of returning true/false values.

Thanks.

I wrote some functions for an ftp server for windows called GuildFTPd.

Here they are, they are pretty much so self explanitory:
<?
function guildftpd_adduser($ftp_stream,$group,$username,$password){
    ftp_site($ftp_stream,"SITE ADDUSER $group $username $password");
}
function guildftpd_addgroup($ftp_stream,$groupname){
    ftp_site($ftp_stream,"SITE ADDGROUP $groupname");
}
function guildftpd_deluser($ftp_stream,$username){
    ftp_site($ftp_stream,"SITE DELUSER $username");
}
function guildftpd_addpath($ftp_stream,$username,$path,$vpath){
    ftp_site($ftp_stream,"SITE ADDPATH $username $path $vpath");
}
function guildftpd_delpath($ftp_stream,$username,$path,$vpath){
    ftp_site($ftp_stream,"SITE DELPATH $username $path $vpath");
}
function guildftpd_anon($ftp_stream){
    ftp_site($ftp_stream,"SITE ANON ALLOW");
}
function guildftpd_anond($ftp_stream){
    ftp_site($ftp_stream,"SITE ANON DENY");
}
function guildftpd_chpass($ftp_stream,$user,$pass){
    ftp_site($ftp_stream,"SITE CHPASS $user $pass");
}
function guildftpd_disable($ftp_stream,$user){
    ftp_site($ftp_stream,"SITE DISABLE $user");
}
function guildftpd_enable($ftp_stream,$user){
    ftp_site($ftp_stream,"SITE ENABLE $user");
}
function guildftpd_who($ftp_stream){
    $who = ftp_site($ftp_stream,"SITE WHO");
}
function guildftpd_kick($ftp_stream,$user);
    ftp_site($ftp_stream,"SITE KICK $user");
}
function guildftpd_msg($ftp_stream,$text);
    ftp_site($ftp_stream,"SITE MSG $text");
}
?>
