For directly inserting content into a file on an FTP host, you could also create a string stream wich streams directly to the ftp_fput function. 
This should create less overhead than first writing to any temp directories locally before streaming, as suggested here. 

If when using fput you get the one of the following errors:
Warning: ftp_fput() [function.ftp-fput]: Opening ASCII mode data connection
Warning: ftp_fput() [function.ftp-fput]: Opening BINARY mode data connection
and it creates the file in the correct location but is a 0kb file and all FTP commands thereafter fail. It is likely that the client is behind a firewall. To rectify this use:

Before executing any put commands. Took me so long to figure this out I actually cheered when I did :D

Make sure you chdir to remote directory before using ftp_put or else ftp_put will just return error that it cannot create file. After you do the chdir you should NOT pass the whole path of file to ftp_put but just basename (filename). See example for more info.
Example: 

When you have your file contents as a string, create temporary stream and use that as a file handle. 

This might be obvious to most of you, but make sure your stream isn't write-only. It has to be able to read from your stream in order to upload its contents.
Took me a while trying to figure out why my uploaded file was 0B, and that was why.

Fails if destination file exists. Delete first and it works.

You might also want to note that ftp_fput will overwrite any existing file.

Using jopi paranoid fi's example, tmpfile() works on PHP 4 and 5 instead of using the php://temp file.

This is a function i wrote to copy a complete directory to a FTP-Server-folder.
function ftp_uploaddirectory($conn_id, $local_dir, $remote_dir)
{
 @ftp_mkdir($conn_id, $remote_dir);
 $handle = opendir($local_dir);
 while (($file = readdir($handle)) !== false)
 {
  if (($file != '.') && ($file != '..'))
  {
   if (is_dir($local_dir.$file))
   {
    ftp_uploaddirectory($conn_id, $local_dir.$file.'/', $remote_dir.$file.'/');
   }
   else
    $f[] = $file;
  }
 }
 closedir($handle);
 if (count($f))
 {
  sort($f);
  @ftp_chdir($conn_id, $remote_dir);
  foreach ($f as $files)
  {
   $from = @fopen("$local_dir$files", 'r');
   @ftp_fput($conn_id, $files, $from, FTP_BINARY);
  }
 }
}
Example:
$conn_id = @ftp_connect($server);
@ftp_login ($conn_id, $username, $passwort);
ftp_uploaddirectory($conn_id, 'mydirectory/', 'theftpdirectory/');
@ftp_quit($conn_id);
I hope you'll find it useful.

If you want to pass a string containing the filename as source and not a resource handle use ftp_put() instead. Trivial but not mentioned here.
