複数ファイルのアップロード
Hello PHP World After many Hours of worryness :=)
I have found the Solution for Resume or Pause Uploads
In this Code Snippet it is the Server Side not Client on any Desktop Programm you must use byte ranges to calculate the uploaded bytes and missing of total bytes.
Here the PHP Code
<?php
$CHUNK = 8192;
try {
if (!($putData = fopen("php://input", "r")))
throw new Exception("Can't get PUT data.");
// now the params can be used like any other variable
// see below after input has finished
$tot_write = 0;
$tmpFileName = "/var/dev/tmp/PUT_FILE";
// Create a temp file
if (!is_file($tmpFileName)) {
fclose(fopen($tmpFileName, "x")); //create the file and close it
// Open the file for writing
if (!($fp = fopen($tmpFileName, "w")))
throw new Exception("Can't write to tmp file");
// Read the data a chunk at a time and write to the file
while ($data = fread($putData, $CHUNK)) {
$chunk_read = strlen($data);
if (($block_write = fwrite($fp, $data)) != $chunk_read)
throw new Exception("Can't write more to tmp file");
$tot_write += $block_write;
}
if (!fclose($fp))
throw new Exception("Can't close tmp file");
unset($putData);
} else {
// Open the file for writing
if (!($fp = fopen($tmpFileName, "a")))
throw new Exception("Can't write to tmp file");
// Read the data a chunk at a time and write to the file
while ($data = fread($putData, $CHUNK)) {
$chunk_read = strlen($data);
if (($block_write = fwrite($fp, $data)) != $chunk_read)
throw new Exception("Can't write more to tmp file");
$tot_write += $block_write;
}
if (!fclose($fp))
throw new Exception("Can't close tmp file");
unset($putData);
}
// Check file length and MD5
if ($tot_write != $file_size)
throw new Exception("Wrong file size");
$md5_arr = explode(' ', exec("md5sum $tmpFileName"));
$md5 = $md5sum_arr[0];
if ($md5 != $md5sum)
throw new Exception("Wrong md5");
} catch (Exception $e) {
echo '', $e->getMessage(), "\n";
}
?>
PUT メソッドのサポート
PHP は、クライアントがサーバーにファイルを保存するための HTTP PUT メソッドのサポートを提供します。 PUT リクエストは POST リクエストによるファイルアップロードよりもシンプルであり、 次のような形になります。
PUT /path/filename.html HTTP/1.1
これは、通常、リモートクライアントが /path/filename.html が指す内容を Web ツリーに保存したいことを意味します。 Apache または PHP に おいて全ての人が Web ツリー上の任意のファイルを自動的に上書きできる ようにするというのは明らかに良い発想ではありません。よって、このような リクエストを処理する際には、まずそのリクエストを処理する特定の PHP スクリプトが必要なことを web サーバーに通知する必要があります。 Apache においては、Script ディレクティブにより これを行うことができます。これは、Apache 設定ファイルのほぼ任意の 場所に置くことができます。一般的なのは、<Directory> ブロックまたは <VirtualHost> ブロックの中です。次のように指定します。
Script PUT /put.php
これにより、この行を指定したコンテキストにマッチする URI を有する すべての PUT リクエストが put.php スクリプトに送られるよう Apache に 指定します。 もちろん、拡張子 .php により PHP が実行されるよう設定され、 PHP がアクティブであることが必要です。 このスクリプトに対するすべての PUT リクエストの対象リソースは、 スクリプト自身とします。アップロードされるファイルのファイル名ではありません。
PHP では、put.php の中で以下のようなことを行います。 これは、アップロードされたファイルをサーバー上のファイル myputfile.ext にコピーします。 ファイルコピーを行う前には、 何らかの確認やユーザー認証を行いたくなるかもしれません。
例1 HTTP PUT されたファイルの保存
<?php
/* PUT されたデータは標準入力からやってきます */
$putdata = fopen("php://input", "r");
/* 書き込みモードでファイルをオープンします */
$fp = fopen("myputfile.ext", "w");
/* データを 1 KB 単位で読み込み、
ファイルに書き込みます */
while ($data = fread($putdata, 1024))
fwrite($fp, $data);
/* ストリームを閉じます */
fclose($fp);
fclose($putdata);
?>

I have spent a lot of time trying to make PUT work with Apache 2.0.40. I have not yet been able to find any way of making the Script directive invoke php via mod_php, the only way has been to have a file called example.cgi and invoke it via CGI, with the file starting
#!/usr/bin/php
so the PHP interpreter is invoked through the CGI mechanism and not as a module.
If there IS a way of making it work 'right' I'd love to know! After six hours of messing around, I've settled for CGI. The error messages in the apache error log are significantly misleading and the whole thing has been an exercise in frustration.
Attempts to use AddHandler and all 'normal' ways of trying to persuade Apache to do this have been fruitless. It does seem as if PUT can only be handled by CGI invocation.

PUT raw data comes in php://input, and you have to use fopen() and fread() to get the content. file_get_contents() is useless.
The HTTP PUT request MUST contain a Content-Length header to specify the length (in bytes) of the body, or the server will not be able to know when the input stream is over. This is the common problem for many to find the php://input empty if no such header available.
This should make PUT work properly on win32 using PHP5.1.1 and apache2.

NOTE: The <Script>-Directive can not be placed in .htaccess files.
So if you're having shared webspace and no access to the apache-configuration file you will have little chance to make something like this work.
But you can solve the problem, using mod_rewrite (for Apache) - for further information see the documentation at http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html

A Case Study: To set up publishing with Netscape 7.2 Composer to Apache/PHP, no need to use CGI (which I tried unsuccessfully for too long) or to alter Apache's httpd.conf. I needed only to click Publish As, fill in put2disk.php as the filename (where its contents are the below), and fill in that file's dir as the "Publishing address".
XAMPP 1.4.14: Apache/2.0.54 (Win32) mod_ssl/2.0.54 OpenSSL/0.9.7g PHP/5.0.4.
<? // filename: put2disk.php.
//file_put_contents ("get_def.out", print_r (get_defined_vars(), TRUE)); // debugging
// Two slurp methods: (a) didn't work, (b) did.
//$stdin_rsc = fopen("php://input", "r");
//$putdata='';
//while ($putdata .= fread($stdin_rsc, 1024)); // a. Hangs the "Publishing..." dialog.
//while (!feof($stdin_rsc)) $putdata.=fread($stdin_rsc, 8192); // b. Worked, but file_get_contents is faster.
//fclose($stdin_rsc);
// All that's nec:
$putdata=file_get_contents('php://input'); // Not php://stdin! (When the ability to see error messages isn't available, the doc (this manual page) needs to be more accurate.)
file_put_contents("stdin.out",$putdata);
?>

I can only make it work when I am using PHP as CGI, not as an Apache module.
I am using the version of PHP/Apahce that is shipped with Debian/testing.
You have to load the action_module, but not the put_module in Apache config.

Here's my solution on my Note below
The .htacces-File
Options FollowSymLinks
RewriteEngine on
RewriteBase !!!The Path of your PUT-Upload-Folder, relative to the DocumentRoot!!!
RewriteRule ^index\.php$ - [L]
RewriteRule ^(.*)$ index.php?url=$1 [L]
index.php:
<?php
if ($_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'])); }
?>

Trying to capture a PUT stream into a single variable seems not to be allowed, probably because of the non presence of some kind of EOF. In this way save a PUT request into a database isn't easy.
The only way I find would be output to a cache file, then either insert filename into db or read again its content and place it in some kind of query.
