doing an http post

For the benefit of others, I want to show how to do
an HTTP POST request using fsockopen(). I banged my
head against a wall for two days trying to figure
this out. I even went to http://php.net/ to find
out how to do this, but it didn't help because
my mind automagically converted the "Content-Length"
header into "Length."

I even went to http://www.ietf.org/ to find out
the specific protocol for HTTP POSTs, but I didn't
find it there. RFC 2616 (HTTP) does not give the
exact format for POST requests.

Question: Where is the format for POST requests defined?

---------------- send_post.php ---------------
// file: send_post.php
error_reporting (E_ALL & ~E_NOTICE);
$eol = "\r\n";
$errno = 0;
$errstr = '';
$data = 'username=georg e&password=i81b pz';
$fid = fsockopen('loca lhost', 8080, &$errno, &$errstr, 30);
if ($fid) {
fputs ($fid, "POST /post/show_post.php HTTP/1.1$eol");
fputs ($fid, "HOST: localhost$eol") ;
fputs ($fid, "Connection : close$eol");
fputs ($fid, "Content-Type: application/x-www-form-urlencoded$eol" );

// Use 'Content-Length' NOT 'Length' !
fputs ($fid, 'Content-Length: ' . strlen($data) . $eol);
fputs ($fid, $eol);
fputs ($fid, $data);
fputs ($fid, $eol);
fpassthru($fid) ;


------------- show_post.php -----------------
// file: show_post.php
error_reporting (E_ALL & ~E_NOTICE);

echo "<pre>\n";
echo "------------ POST VARIABLES ----------\n";
print_r($HTTP_P OST_VARS);
echo "------------ SERVER VARIABLES ----------\n";
print_r($HTTP_S ERVER_VARS);
echo "</pre>\n";

Use curl instead.

What an amazingly helpful answer.

Try something like this? :

function PostToHost($hos t, $path, $data_to_send) {
$fp = fsockopen($host ,80);
fputs($fp, "POST $path HTTP/1.1\n" );
fputs($fp, "Host: $host\n" );
fputs($fp, "Content-type: application/x-www-form-urlencoded\n" );
fputs($fp, "Content-length: ".strlen($data_ to_send)."\n" );
fputs($fp, "Connection : close\n\n" );
fputs($fp, $data_to_send);

There is no signature.....

The RFC in question is RFC2616, which is the HTTP/1.1 specification and
can be found here:

<Xn************ *************@2>, the AI program named "Phil
Roberts" <ph*****@holyfl atnetshit.net> randomly printed:
fputs($fp, "POST $path HTTP/1.1\n" );
fputs($fp, "Host: $host\n" );

I thought that the end of line sequence was
\r\n not just \n.

I am programming what is to be a web service client that will use an HTTP-POST to request and retrieve data.
