As stream_copy_to_stream() seems to be quite a memory hog (at least in PHP 5.1.6 64-bit) it may be way more efficient just to copy streams with this simple PHP alternative:
<?php
function pipe_streams($in, $out)
{
$size = 0;
while (!feof($in)) $size += fwrite($out,fread($in,8192));
return $size;
}
?>

If you need to copy a file from any website into yours you can use following function:
function getUrlContents($url)
{
$url_parsed = parse_url($url);
$host = $url_parsed["host"];
if ($url == '' || $host == '') {
return false;
}
$port = 80;
$path = (empty($url_parsed["path"]) ? '/' : $url_parsed["path"]);
$path.= (!empty($url_parsed["query"]) ? '?'.$url_parsed["query"] : '');
$out = "GET $path HTTP/1.0\r\nHost: $host\r\nConnection: Close\r\n\r\n";
$fp = fsockopen($host, $port, $errno, $errstr, 30);
fwrite($fp, $out);
$headers = '';
$content = '';
$buf = '';
$isBody = false;
while (!feof($fp) and !$isBody) {
$buf = fgets($fp, 1024);
if ($buf == "\r\n" ) {$isBody = true;}
else{$headers .= $buf;}
}
$file1 = fopen(basename($url_parsed["path"]), 'w');
$bytes=stream_copy_to_stream($fp,$file1);
fclose($fp);
return $bytes;
}

stream_copy_to_stream almost copies a stream...
$objInputStream = fopen("php://input", "rb");
$objTempStream = fopen("php://temp", "w+b");
stream_copy_to_stream($objInputStream, $objTempStream);
That code will copy a stream but it will also move the stream pointers to EOF. This is fine if you plan on rewinding the temp stream but good luck rewinding the input stream.
rewind($objTempStream);
rewind($objInputStream);
So as you can see this is stream copy or stream move depending on what kind of stream you are working with, and because there are no peaking functions your effed if you need to read from an input stream in multiple classes that are unrelated.
