simulate post information including username and password thru php

[j_smith123]

hi

I am trying to simulate POST thru php but the script will not work because I need to specify the login credentials (username and password) of the site I am contacting. The problem is that I am not sure where I should specify these.

below is the code that I am using :
.............................................................................

<?php 
////////////////////////////////////////////////////
function post_it($datastream, $url) 
{ 
	//.... process the destination URL first .... //
	// remove http:// from the url
	$url = preg_replace("@^http://@i", "", $url); 
	// extract everything that is before 
	// the first / once http:// has been removed
	$host = substr($url, 0, strpos($url, "/")); 
	// the location of the page on the server.
	$uri = strstr($url, "/"); 
	///////////////////////////////////////////////

// variable which will contain all the POST 
// variables and their values	
$reqbody = ''; 	
foreach($datastream as $key=>$val) 
{ 
  if (!empty($reqbody)) $reqbody.= '&'; 
	$reqbody.= $key.'='.urlencode($val); 
} 

$contentlength = strlen($reqbody); 
$reqheader = "POST $uri HTTP/1.1\r\n". 
			 "Host: $host\n". "User-Agent: PostIt\r\n". 
			 "Content-Type: application/x-www-form-urlencoded\r\n". 
			 "Content-Length: $contentlength\r\n\r\n". 
			 "$reqbody\r\n";
			 //"Connection: Close";

// open a socket connection to the server at port 80
$socket = fsockopen($host, 8000, $errno, $errstr); 

if (!$socket) 
{ 
	$result["errno"] = $errno; 
	$result["errstr"] = $errstr; 
	return $result; 
} 
// post the infornation on the server
fputs($socket, $reqheader); 

// get the ouput generated, after the script 
// has processed the POST variables on the server,
// in an array
while (!feof($socket)) 
{ 
	$result[] = fgets($socket, 4096); 
} 

fclose($socket); 	
return $result; 	
} 												
////////////////////////////////////////////////

// the data that you want the script on the remote server to process


$data['Page'] = 'FinalizeUser' ;
$data['ReturnPage'] = 'UserQry';
$data['Title'] 	= 'User%20Search';
$data['UserId'] = 'aspclient';
$data['AccountIndex'] = '13';
$data['Confirm'] = 'Confirm';

// send the data to the script
$result = post_it($data, "http://localhost/Admin"); 
if (isset($result["errno"])) 
{ 
	$errno = $result["errno"]; 
	$errstr = $result["errstr"]; 
	echo "<B>Error $errno</B> $errstr"; 
	exit; 
} 
else 
{ 
	// display from row 11 onwards because
	// rows 1-10 contain the header information.
	// Rows 11 onwards will contain the ouput of 
	// the script on the remote server
	for($i=0;$i< count($result); $i++) 
	{
		echo $result[$i]; 
	}
} 
//}	
?>

..............................................................................

The reply that I get is:

HTTP/1.0 401 Unauthorized Server: Extent/1.0 WWW-Authenticate: Basic realm="TestWebServer" Content-type: text/html Access denied

Now, I do know the username and password to use, but where do I specify these?

I have tried: http://admin:password@localhost/Admin"

but it does not work, I get the following error:

Warning: fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: No such host is known.

I am using PHP Version 5.0.2 on Windows 2000 Server and IIS 5.0.

Hearty thanks to anyone who can help.
