how to pass STDIN to php

WittRaider

I am currently developing a webserver based on PHP. Implementing CGI I am running into a few problems with POST data which is supposed to be passed to PHP via the STDIN, according to the CGI spec (http://cgi-spec.golux.com/draft-coar-cgi-v11-03-clean.html#6.2). I am on a Win2K machine and using the prefered way of appending "< FileWithPostData.txt" does not seem to work.

If anyone has an idea how to get PHP to read the POST data, plz let me know. populating "HTTP_RAW_POST_DATA" via putenv() did not help for the $_POST array to be populated.

Using php 4.3 you have 3 new constants defined, STDIN, STDOUT and STDERR. So you can do something like:

$stdin = trim(fgets(STDIN, 256)); 
print $stdin;

or even

fwrite(STDERR, "writing to stderr\n");

If you are using PHP < v4.3 then you can define these yourself, like:

define('STDIN',  fopen("php://stdin",  "r"));
define('STDOUT', fopen("php://stdout", "r"));
define('STDERR', fopen("php://stderr", "r"));

Oops! Sorry, I took a quick glance and saw the word STDIN but didn't see the word POST....

shell_exec('echo $postdata | php.exe script.php');

Doing this does not throw and error and at least doesn't make PHP freeze (which it did because it was trying to read something from SDTIN when the CONTENT_LENGTH envvar was set). But it on the other hand does not cause for PHP to register the vars in the $_POST array.

p.s.: tried it with the filename as well, which cannot work ;-)
