Warning: implode() [function.implode]: Invalid arguments passed

[QWaz]

Hi,

I am getting this error:

Warning: implode() [function.implode]: Invalid arguments passed in ... on line 28

I am not sure if what I am doing is possible or if I have shanked the code somehow..

if(!isset($_GET['b'])) {
        ///// DISPLAY THE NORMAL PROMOTIONAL HOME PAGE
} elseif($_GET['b'] == 't') {

$sql = "SELECT * FROM brands";
$setBrand=array();
foreach ($conn->query($sql) as $row) {   
$setBrand[]=<<<END
    <div class="brandRowM">
        <div class="brandRow">
            <div class="brand"><a href="#">$row[brand]</a></div><br />
            <div class="productSmPic">
                <ul>
END;
    $sql = "SELECT * FROM products WHERE top = '1' && brand = '".$row['brand']."'";
            foreach ($conn->query($sql) as $info) {   
            $setInfo[]=<<<END
                    <li><a href="product.php"><img src="$info[PFN1]" width="100px" height="60px" /></a>
                        <ul>
                            <li><div class="productSmName">$info[name]</div></li>
                            <li><div class="productSmCode">$info[icode]</div></li>
                            <li><div class="productSmRRP">RRP: $$info[cost]</div></li>
                            <li><div class="productSmQRP">Click to see price</div></li>
                        </ul>
                    </li>
END;
            }
            $setInfo=implode("\r\n",$setInfo);

<<<END
                </ul>    
            </div>        
        </div>
    </div>
END;
    }
    $setBrand=implode("\r\n",$setBrand);

}

I have been trying to get this work for a while now, so any help would be SSOOOO appreciated.

Cheers,
