if( !defined( 'MEDIAWIKI' ) ) {
        echo( "This is an extension to the MediaWiki package and cannot be run standalone.\n" );
        die( -1 );
}

// This is the prefix used for database names for the wiki farm
$dbprefix = ''; // This prefix is for the name of the database, not for the tables!

// Database user that can create databases
$dbcreateUser = ''; // For security, this is all that this user should be able to do; do not use root!
$dbcreateUserPassword = ''; // Password of this user

// Get the information about the new wiki from the form
$wikiName = $_POST['wikiName'];
$userName = $_POST['userName'];
$userPass = $_POST['userPass'];
$wikiDomain = $_POST['wikiDomain'];

// Convert the wiki domain string to lowercase with first capital letter for use as the database name
$wikiDomain = ucfirst(strtolower($wikiDomain));

$wikiName = escapeshellcmd($wikiName);
$userName = escapeshellcmd($userName);
$userPass = escapeshellcmd($userPass);

rename('LocalSettings.php','LocalSettings1.php');

shell_exec('WIKI='.$dbprefix,$wikiName.' php maintenance/install.php '.$wikiName.' '.$userName.' --pass='.$userPass.' --dbname='.$dbprefix,$wikiName.' --dbprefix='.$wgDBprefix.'  --dbuser='.$wgDBuser.' --dbpass='.$wgDBpassword.'');

unlink('LocalSettings.php');

rename('LocalSettings1.php','LocalSettings.php');

?>

POSSIBLE SECURITY FLAW ALERT:

Per http://php.net/manual/en/function.escapeshellcmd.php it seems escapeshellarg should be used, or:

$escapedshellcmd = escapeshellcmd('WIKI='.$dbprefix,$wikiName.' php maintenance/install.php '.$wikiName.' '.$userName.' --pass='.$userPass.' --dbname='.$dbprefix,$wikiName.' --dbprefix='.$wgDBprefix.'  --dbuser='.$wgDBuser.' --dbpass='.$wgDBpassword.'');

shell_exec($escapedshellcmd);
