There are many small errors in your code. Here's a snippet which is tested and works.

<pre><code>&lt;?php

$fp = fsockopen('example.com', 80);

$vars = array(
 'hello' =&gt; 'world'
);
$content = http_build_query($vars);

fwrite($fp, "POST /reposter.php HTTP/1.1\r\n");
fwrite($fp, "Host: example.com\r\n");
fwrite($fp, "Content-Type: application/x-www-form-urlencoded\r\n");
fwrite($fp, "Content-Length: ".strlen($content)."\r\n");
fwrite($fp, "Connection: close\r\n");
fwrite($fp, "\r\n");

fwrite($fp, $content);

header('Content-type: text/plain');
while (!feof($fp)) {
 echo fgets($fp, 1024);
}
</code></pre>

And then at example.com/reposter.php put this

<pre><code>&lt;?php print_r($_POST);
</code></pre>

When run you should get output something like

<pre><code>HTTP/1.1 200 OK

For those that also need to send get vars along with the url, 

<pre><code>//change this:

Try this in reposter.php

<pre><code>$raw_data = $GLOBALS['HTTP_RAW_POST_DATA']; 
parse_str( $raw_data, $_POST );

Because, the data wasn't in the <code>$_POST[]</code> variables but it was in the <code>$GLOBALS['HTTP_RAW_POST_DATA']</code> variable.

I am attempting to post data using fsockopen, and then returning the result.
Here is my current code:

<pre><code>&lt;?php
$data="stuff=hoorah\r\n";
$data=urlencode($data);

$fp = fsockopen("www.website.com", 80, $errno, $errstr, 30);
if (!$fp) {
 echo "$errstr ($errno)&lt;br /&gt;\n";
} else {
 $out = "POST /script.php HTTP/1.0\r\n";
 $out .= "Host: www.webste.com\r\n";
 $out .= 'Content-Type: application/x-www-form-urlencoded\r\n';
 $out .= 'Content-Length: ' . strlen($data) . '\r\n\r\n';
 $out .= "Connection: Close\r\n\r\n";
 fwrite($fp, $out);
 while (!feof($fp)) {
 echo fgets($fp, 128);
 }
 fclose($fp);
}
?&gt; 
</code></pre>

It is supposed to echo the page, and it is echoing the page, but here is the script for script.php

<pre><code>&lt;?php
echo "&lt;br&gt;&lt;br&gt;"; 
$raw_data = $GLOBALS['HTTP_RAW_POST_DATA']; 
 parse_str( $raw_data, $_POST );

//test 1
var_dump($raw_data);
echo "&lt;br&gt;&lt;br&gt;":
//test 2
print_r( $_POST ); 
?&gt;
</code></pre>

The outcome is:

<blockquote>
 HTTP/1.1 200 OK Date: Tue, 02 Mar 2010

What do I have wrong? Why isn't the variable posting its data?
