I'm working on a real frankensite here not of my own design. There's a rudimentary CMS and one of the pages shows customer records from a MySQL DB.

For some reason, it has no probs picking up the data from the DB - there's no duplicate records - but it renders each row twice.

<?php
$limit = 500;
$area = 'customers_list';
$prc = 'customer_list.php';

if($_GET['page'])
{
    include('inc/functions.php');
    $page = $_GET['page'];
}
else 
{
    $page = 1;
}

$limitvalue = $page * $limit - ($limit);

$customers_check = get_customers();
$customers = get_customers($limitvalue, $limit);
$totalrows = count($customers_check);

?>
<!-- pid: customer_list -->

<table border="0" width="100%" cellpadding="0" cellspacing="0" style="float: left; margin-bottom: 20px;">
    <tr>
        <td class="col_title" width="200">Name</td>
        <td></td>

        <td class="col_title" width="200">Town/City</td>
        <td></td>

        <td class="col_title">Telephone</td>

        <td></td>
    </tr>

    <?php
    for ($i = 0; $i < count($customers); $i++)
    {
    ?>
    <tr>
        <td colspan="2" class="cus_col_1"><a href="customer_details.php?id=<?php echo $customers[$i]['customer_id']; ?>"><?php echo $customers[$i]['surname'].', '.$customers[$i]['first_name']; ?></a></td>
        <td colspan="2" class="cus_col_2"><?php echo $customers[$i]['town']; ?></td>
        <td class="cus_col_1"><?php echo $customers[$i]['telephone']; ?></td>

        </td>
    </tr>
    <tr><td class="col_divider" colspan="6"></td></tr>
    <?php

I'm not the world's best PHP expert but I think I can see an error in a for loop when there is one... But everything looks ok to me. You'll notice that the customer name is clickable; clicking takes you to another page where you can view their full info as held in the DB - and for both rows, the customer ID is identical, and manually checking the DB shows there's no duplicate entries. The code is definitely rendering each row twice, but for what reason I have no idea.

All pointers / advice appreciated.

The page PHP is viewable at http://christopher.pastebin.com/DQkjjG3s (attempted to include in this post but it was horribly mangled, think it's important to have it all in context).
