         echo '<br/>'."
".'<br/>'."
".'<br/>'."
";   

    }

One thing you can do is break the foreach loop when a counter reaches 10.

$i = 0;
foreach ($itemList as $item) {
    $i++;
    // ...
    if($i>9){ break; }
}

Or, restructure into a for() loop, and surround ALL the code inside with an if() statement similar to above.
