Use $_POST when PHP is running in the context of a webserver. If you use
PHP from the command line there will be no $_POST.

Hello,
I read that passing data via POST means PHP running as CGI needs to
read from standard input buffer instead of global vars. I tried reading
from $_POST but can't find my data there.

I searched the manual for a function to read from stdin but couldn't
find any. Does it even exist or do we always use $_POST?

Any help is appreciated,
Hobart

You don't want it in this case, but reading from stdin:
$fp = fopen('php://stdin', 'r');
while($line = fgets($fp, 4096) { echo $line; }

HTH,

Thanks for clearing that up, Matthias. However I still this problem...

My script gets run when a form is submitted. If action="write.php",
everything works fine - I can read $_POST["data"].

If action="write.cgi", the script runs and prints out the hardcoded text
but when echoing $_POST["data"] nothing comes out.

What could possibly be the reason?

PHP is not invoked when the script is named .cgi?

You can run PHP either as an Apache module (how it usually is), or as a CGI
app.

Yes, but my scripts still have the extension ".php", even when I use PHP
as a CGI application.

Yea, my host requires all cgi scripts to be names *.cgi for security
reasons.
