ftp_site

说明

bool ftp_site ( resource ftp_stream, string cmd )

ftp_site() 函数向 FTP 服务器发送由参数 cmd 指定的命令。SITE 命令是非标准化的，不同的服务器不尽相同。主要用于处理文件权限以及组成员等事情。

例子 1. 向一个 FTP 服务器发送一条 SITE 命令


<?php
/* Connect to FTP server */
$conn = ftp_connect('ftp.example.com');
if (!$conn) die('Unable to connect to ftp.example.com');

/* Login as "user" with password "pass" */
if (!ftp_login($conn, 'user', 'pass')) die('Error logging into ftp.example.com');

/* Issue: "SITE CHMOD 0600 /home/user/privatefile" command to ftp server */
if (ftp_site($conn, 'CHMOD 0600 /home/user/privatefile')) {
   echo "Command executed successfully.\n";
} else {
   die('Command failed.');
}
?>

如果成功则返回 TRUE，失败则返回 FALSE。

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

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");

}

?>

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!

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.

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
