php ftp制作多个目录

Here is my PHP code. It actually works fine:

            $newftpdir_parent   = date('Ymd');                              // YYYYMMDD
            $newftpdir_child    = $ext_folder;                              // username
            $newftpdir          = $newftpdir_parent.'/'.$newftpdir_child;   // YYYYMMDD/username
            $conn_id            = ftp_connect($uptoftp_server);
            ftp_login($conn_id, $uptoftp_username, $uptoftp_pass);

            $path_of_storage    = $uptoftp_path_abs.'/'.$uptoftp_path_rel; // /var/www/uploads
            if( !@ftp_chdir($conn_id, $path_of_storage.'/'.$newftpdir_parent) ){
                  ftp_mkdir($conn_id, $path_of_storage.'/'.$newftpdir_parent);
                  ftp_chmod($conn_id, 0777, $path_of_storage.'/'.$newftpdir_parent);
            }
            if( !@ftp_chdir($conn_id, $path_of_storage.'/'.$newftpdir) ){
                  ftp_mkdir($conn_id, $path_of_storage.'/'.$newftpdir);
                  ftp_chmod($conn_id, 0777, $path_of_storage.'/'.$newftpdir);
            }

            ftp_chdir($conn_id, $path_of_storage.'/'.$newftpdir);

            ftp_put($conn_id, $file_name, $filetoftp, FTP_ASCII);

            ftp_close($conn_id);

It uploads a file from local server to remote ftp servers. As you can se there are 2 ugly if conditions that check if directory exists, if not we create it and move in it. And again for subdir. Since I now want my directories (on the ftp servers) to look like YYYY/MM/DD/username instead of YYYYMMDD/username, I will need to create two more of these if blocks. It works great, but it does not look clean, I'm kind of maniac about it... I was wondering if there is better way to do it, since ftp_mkdir() cannot make multiple dirs (dir with subdirs in it)?

for exemple, considering only the /uploads/ dir exists, but not the /2013/ neither subdir /06/ and /11/ :

ftp_mkdir($conn_id, '/var/www/uploads/2013/06/11');

returns:

Warning: ftp_mkdir() [function.ftp-mkdir]: /var/www/uploads/2013/06/11: No such file or directory in /home/blabla/www/test.php on line 18

<?php

// function
function ftp_mksubdirs($ftpcon,$ftpbasedir,$ftpath){
   @ftp_chdir($ftpcon, $ftpbasedir); // /var/www/uploads
   $parts = array_filter(explode('/',$ftpath)); // 2013/06/11/username
   foreach($parts as $part){
      if(!@ftp_chdir($ftpcon, $part)){
         ftp_mkdir($ftpcon, $part);
         //ftp_chmod($ftpcon, 0775, $part);
         ftp_chdir($ftpcon, $part);
      }
   }
}

// usage
$path_of_storage = '/var/www/uploads';
$newftpdir = '2013/06/11/username';

$conn_id = ftp_connect($ftpserver);
ftp_login($conn_id, $login, $pass);
ftp_mksubdirs($conn_id,$path_of_storage,$newftpdir);
ftp_close($conn_id);

?>

Found this, maybe it helps:

function ftp_mkdir_recusive($con_id,$path){
    $parts = explode("/",$path);
    $return = true;
    $fullpath = "";
    foreach($parts as $part){
            if(empty($part)){
                    $fullpath .= "/";
                    continue;
            }
            $fullpath .= $part."/";
            if(@ftp_chdir($con_id, $fullpath)){
               ftp_chdir($con_id, $fullpath);
            }else{
                    if(@ftp_mkdir($con_id, $part)){
                            ftp_chdir($con_id, $part);
                    }else{
                            $return = false;
                    }
            }
    }
    return $return;
}

$dir = "/2012/05/02/"

if(ftp_mkdir_recusive($con_id,$dir)){
     print("Successfully created $dir");
}else{
    print("There was a problem while creating $dir");
}
