php://input allows you to read raw POST data. It is a less memory intensive alternative to $HTTP_RAW_POST_DATA and does not need any special php.ini directives.
Example use:
$httprawpostdata = file_get_contents("php://input");
When reading a base64 encoded stream using php://input, be aware that you do not need to decode it, it will automatically be done for you.
附录 L. 支持的协议／封装协议列表
以下是 PHP 内置用于文件系统函数例如 fopen() 和 copy() 的 URL 风格协议列表。除了这些封装协议之外，从 PHP 4.3 起，还可以用 PHP 脚本和 stream_wrapper_register() 写自己的封装协议。
文件系统
所有版本的 PHP。自 PHP 4.3.0 以来明确使用 file://。
/path/to/file.ext
relative/path/to/file.ext
fileInCwd.ext
C:/path/to/winfile.ext
C:\path\to\winfile.ext
\\smbserver\share\path\to\winfile.ext
file:///path/to/file.ext
file:// 是 PHP 默认的描述本地文件系统的封装协议。指定相对路径 (相对路径名不开始于 /、\、\\ 或 Windows 盘符) 时，该路径是相对于当前的工作目录。在很多情况下工作目录就是当前执行的脚本所在的目录，除非它被改变。使用 CLI sapi 时，默认是调用该脚本时终端所处的目录。
某些函数，例如 fopen() 和 file_get_contents()，会自动搜索 include_path 作为相对路径。

php://stdin supports fseek() and fstat() function call,
while php://input doesn't.

Be aware that contrary to the way this makes it sound, under Apache, php://output and php://stdout don't point to the same place.
<?php
$fo = fopen('php://output', 'w');
$fs = fopen('php://stdout', 'w');
fputs($fo, "You can see this with the CLI and Apache.\n");
fputs($fs, "This only shows up on the CLI...\n");
fclose($fo);
fclose($fs);
?>
Using the CLI you'll see:
You can see this with the CLI and Apache.
This only shows up on the CLI...
Using the Apache SAPI you'll see:
You can see this with the CLI and Apache.

If you're looking for a unix based smb wrapper there isn't one built in, but I've had luck with http://www.zevils.com/cgi-bin/viewcvs.cgi/libsmbclient-php/ (tarball link at the end).

When opening php://output in append mode you get an error, the way to do it:
$fp=fopen("php://output","w");
fwrite($fp,"Hello, world !<BR>\n");
fclose($fp);

The contants:
* STDIN
* STDOUT
* STDERR
Were introduced in PHP 4.3.0 and are synomous with the fopen('php://stdx') result resource.

I find using file_get_contents with php://input is very handy and efficient. Here is the code:
$request = "";
$request = file_get_contents("php://input");
I don't need to declare the URL filr string as "r". It automatically handles open the file with read.
I can then use this $request string to your XMLparser as data.

[ Editor's Note: There is a way to know. All response headers (from both the final responding server and intermediate redirecters) can be found in $http_response_header or stream_get_meta_data() as described above. ]
If you open an HTTP url and the server issues a Location style redirect, the redirected contents will be read but you can't find out that this has happened.
So if you then parse the returned html and try and rationalise relative URLs you could get it wrong.
