I alway wanted to look this up. It seems that instead of using 
move_uploaded_file it is preferable to user fopen('php://input') to do 
fileuploads[1]:

<?php

if ($_SERVER['REQUEST_METHOD'] =="PUT")
{$f=fopen(basename($_SERVER['REQUEST_URI']),"w");
$s=fopen("php://input","r");
   while($kb=fread($s,1024))
   {fwrite($f,$kb,1024); }
fclose($f);
fclose($s);
Header("HTTP/1.1 201 Created"); }
elseif ($_SERVER['REQUEST_METHOD'] =="GET")
{readfile(basename($_SERVER['REQUEST_URI'])); }

?>

In a ddition to saving the buffer to a file we could use hash_init, 
hash_update and hash_final to create a hash for it without reading the 
whole thing again. This would also allow us to save the file directly to 
the location we want, without copying it when calling 
OC_Helper::streamCopy(), which should by the way use 
stream_copy_to_stream instead of reimplementing it, right?

seems nice, wanna implement it?


so long
