ftp_site
    (PHP 3>= 3.0.15, PHP 4 )
ftp_site -- Sends a SITE command to the server
Description
bool 
ftp_site ( resource ftp_stream, string cmd)
     ftp_site() sends the command specified by      cmd 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.     
| Example 1. Sending a SITE command to an ftp server | <?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.');
}
 ?> | 
 | 
     Returns TRUE on success or FALSE on failure.
