    ftp_site — Sends a SITE command to the server

    Description

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

    ftp_site() sends the given SITE command to the FTP server.

    SITE commands are not standardized, and vary from server to server. They are useful for handling such things as file permissions and group membership.

    Parameters

    ftp

    An FTP\Connection instance.

    command

    The SITE command. Note that this parameter isn't escaped so there may be some issues with filenames containing spaces and other characters.

    Return Values

    Returns true on success or false on failure.

    Changelog

    Version Description
    8.1.0 The ftp parameter expects an FTP\Connection instance now; previously, a resource was expected.

    Examples

    Example #1 Sending a SITE command to an ftp server

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

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

    // Issue: "SITE CHMOD 0600 /home/user/privatefile" command to ftp server
    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");
    }
    ?>

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

    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

    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");
    }
    ?>
