Why does my SQL query differ when displayed in PHP? - php

Question

When I execute SQL into phpmyadmin, it gives the correct results (as you can see the two order_id's at the first column of the table are different):
However, when I call the SQL into PHP, it displays differently, displaying two rows of order ID #99:
This is the SQL:
SELECT o.order_id,o.farm_id,o.user_id,o.created,u.first_name,u.surname,u.email,
u.telephone_no,ua.user_id,ua.street,ua.town,ua.county,ua.postcode,bc.*
FROM orders o
LEFT JOIN users_address ua
ON ua.user_id = o.user_id
LEFT JOIN users u
ON ua.user_id = u.id
LEFT JOIN basket_checkout bc
ON ua.user_id = bc.user_id
WHERE o.farm_id = 10
AND bc.farm_id = o.farm_id
GROUP BY o.order_id
ORDER BY bc.order_id ASC
This is how I call the SQL into PHP:
<?php $query = "<the query>";
$data_set = mysqli_query($GLOBALS['connection'], $query);
confirm_query2($data_set, $query);
while ($row = mysqli_fetch_array($data_set)) { ?>
<tr>
<!-- Order ID -->
<td class='orders-table' style='font-size:16px;font-weight:bold;'>
<?php echo "<span><a href='{$view_order}.php?id=" . $row['order_id'] . "'>#" . $row['order_id'] . "</a></span>"; ?>
</td>
<!-- Name -->
<td class='orders-table'>
<?php echo "<span>" . $row['first_name'] . " " . $row['surname'] . "</span>"; ?>

<td class='orders-table' style='width:0px;'>
<?php $telephone_no = substr_replace($row['telephone_no'], '-<br />', 4, 0); ?>
<?php echo "<span>0" . str_replace("+44", "", $telephone_no) . "</span>"; ?>

<!-- Street -->

</td>

<td class='orders-table'>
<?php echo "<span>" . "£" . sprintf("%0.2f", $row['produce_total']) . "</a></span>"; ?>
</td>
<!-- Items -->

<?php echo "<span>" . $row['total_items'] . "</a></span>"; ?>
</td>
<!-- Order created -->
<td class='orders-table'>
<?php echo "<span>"; if (date('Y-m-d', strtotime($row['created'])) == date('Y-m-d')) { echo "Today<br />" . date('(H:i)', strtotime($row['created'])); } else { echo date('d/m/y (H:i)', strtotime($row['created'])); } echo "</span>"; ?>
</td>
