Can't pass $_POST values to php-cgi

Question

I'm trying to develop a web server with PHP support so I'm doing some little tests with php-cgi, but I can't pass to the interpreter $_POST values. I've already read this topics, but I couldn't do anything :(:

My source:

export GATEWAY_INTERFACE="CGI/1.1"
export SCRIPT_FILENAME="/home/xzhttpd/htdocs/test.php"
export REQUEST_METHOD="POST"
export REDIRECT_STATUS=200
export SERVER_PROTOCOL="HTTP/1.1"
export REMOTE_HOST="127.0.0.1"
export CONTENT_LENGHT=3
export HTTP_ACCEPT="text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
export CONTENT_TYPE="application/x-www-form-urlencoded"
export BODY="t=1"

exec echo "$BODY" | /usr/bin/php-cgi

I got this:

PHP Notice: Undefined index: t in /home/xzhttpd/htdocs/test.php on line 1

PHP source:

<?php print $_POST["t"]; ?>

useful comment, congratulations, I managed to resolve my problem thanks to you — alkz, Dec 12 '11 at 18:07

You're missing a few more crucial CGI environment variables (it's best to set all of them), which when absent make PHP ignore the request and POST body:

export SCRIPT_NAME="xy.php"
export REQUEST_URI="/xy.php"
export SERVER_NAME="example.com"
export SERVER_PROTOCOL="HTTP/1.1"

That will lead to another PHP warning due to REDIRECT_STATUS=. (Don't remember how that works, probably requires more REDIRECT_* aliases, but one could just disable force-cgi-redirect in the php.ini for testing.)

You have CONTENT_LENGHT misspelled.

It should be CONTENT_LENGTH
