Changing table from URL

Here's my Header code:
<?php header('Content-type: text/html; charset=utf-8'); ?>
<?php

require_once "\\\\frigga/home/users/web/b302/as.pequannock/admin/lib/viewer_functions.php";

list($district_sidebarRecords, $district_sidebarMetaData) = getRecords(array(
'tableName' => 'district_sidebar',
'where' => whereRecordNumberInUrl(1),
'limit' => '1',
));
$district_sidebarRecord = @$district_sidebarRecords[0]; // get first record
?>

Here's the body code:
<h1><?php echo $district_sidebarRecord['title'] ?></h1>
<p><?php echo $district_sidebarRecord['content'] ?></p>

Here's my question:
I have 5 different sites using this page for different content.. but instead of creating 5 of these documents with different table names, I want to use the same document... can't I just put into the link in the URL what table I want it to use?

theres:
district_sidebar
pv_sidebar
pths_sidebar
hv_sidebar
sjg_sidebar

thanks
