I've drawn up a simple script that logs in and fetches information using
the Snoopy class. Snoopy is available at http://snoopy.sourceforge.net/
Simply download the tarball and extract the Snoopy.class.php file in the
same directory as your script. Most important is the getCookieHeaders()
function, which sets up the cookies correctly.
Hope this helps,

<?php
require_once('Snoopy.class.php');
$wikiPath = "http://en.wikipedia.org/w";;
$apiPath = "$wikiPath/api.php";
function getCookieHeaders($headers)
{
// This function parses Snoopy's header array and returns a nice
array of cookies
$cookies = array();
foreach($headers as $header)
if(preg_match("/Set-Cookie: ([^=]*)=([^;]*)/", $header,
$matches))
$cookies[$matches[1]] = $matches[2];
return $cookies;
}
$snoopy = new Snoopy;
// Example 1: Build a table of namespaces
$request_vars = array(
'action' => 'query',
'meta' => 'siteinfo',
'siprop' => 'namespaces',
'sishowalldb' => '',
'format' => 'php' // NEVER, EVER, forget this one
);
if(!$snoopy->submit($apiPath, $request_vars))

$array = unserialize($snoopy->results);
$namespaceArr = $array['query']['namespaces'];
echo "<table border>\n<tr><th>ID</th><th>Name</th></tr>\n";
