ftp_site(ftp, command)

Parameters

`ftp`	`Required.` Specify the FTP connection to use.
`command`	`Required.` Specify the SITE command. Note that this parameter isn't escaped so there may be some issues with filenames containing spaces and other characters.

The example below shows the usage of ftp_site() function.

<?php
//FTP server to use
$ftp_server = "ftp.example.com";

//username for the FTP Connection
$ftp_user = "user";
  
//password for the user
$ftp_pass = "password";
   
//set up a connection or die 
$ftp = ftp_connect($ftp_server)
    or die("Could not connect to $ftp_server");
   
if($ftp) {
  echo "Successfully connected to $ftp_server!\n";
 
  //trying to login
  if(@ftp_login($ftp, $ftp_user, $ftp_pass)) {
    echo "Connected as $ftp_user@$ftp_server\n";

    //trying to send SITE command
    if (ftp_site($ftp, "chmod 777 /temp/file.txt")) {
      echo "Command executed successfully\n";
    } else {
      die('Command failed');
    }

  } else {
    echo "Couldn't connect as $ftp_user\n";
  }
 
  //close the connection
  if(ftp_close($ftp)) {
    echo "Connection closed successfully!\n"; 
  } 
}
?>
