I would like to go to an external site and send a form to it via Post
(simulating having generated the form and having the user submit it). I know
that if I had been using GET, I could just code the parms along with the URL
in the location command. To simulate Post I assume that I just need to use
header to send the POST parms but I do not know the format of what to place
in the header request (and I assume that I then use location to fire off to
connection).
Can someone either supply me with a sample code to do this or give me the
URL of the documentation of the Headers that get sent by Post so I can look
them up and create the needed script myself.
Thank You.

Look up the cURL functions.

use curl (example #2)
see: http://www.php.net/manual/en/function.curl-setopt.php
or file_get_contents
see: http://www.php.net/manual/en/function.file-get-contents.php#108309

Thank You.
Example 2 was EXACTLY what I needed (even though all I wanted to do was pass
a set of parms not load a file).
One other query. I seem to remember a site whose function was to display all
the headers being passed. I think it was a security type page whose purposed
was to show all the data being leaked/sent in the headers when you connect.
I would like to see what I ended up sending (as well as all the headers
being sent) so I have a reference to see what the cURL function caused the
browser to send. Cam you refresh my memory by supplying a URL for that site.
Thank You.

You may be thinking of the HTTP Headers plugin for Firefox. A great
tool, but it doesn't help with cURL because cURL doesn't use the browser.

First of all, when you are using PHP on a website, everything regarding PHP is
executed on the web server, so the users web browser will not do anything more
than send a form to your script.
If you want to have header information which curl sent to the server, you can
do the following before you use curl_close():
$sentheader = curl_getinfo($ch, CURLINFO_HEADER_OUT);
If you want to have the header you got from the remote server, then do the
following before curl_exec():
curl_setopt($ch, CURLINFO_HEADER_OUT, 1);
and before curl_close():
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
If you are interested of seeing the header that the user sent when they posted
the the form:
$headers = apache_request_headers();
foreach ($headers as $header => $value) {
echo "$header: $value <br />\n";
}
This will only work on a apache server, depending on how you have setup the
apache server to execute php. There is suggestion on a work around which you
can read at:

If available - use curl:

<?php
$data = array(
'field1'=>'value1',
'field2'=>'value2'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://server.example');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);
curl_close($ch);
?>

Assuming you have a web server available to you, it shouldn't be too
difficult to set this up yourself. Just make a page on your server that
logs the relevant data to a file, and point your curl routines at that
page.
