Как написать цикл foreach без повторений блока разметки html?

function build_table($array){
    $html = '';
    if (count($array)) {
        foreach( $array as $key=>$value){
            if (count($value)) {
                $html.= '<tr><td>'.implode('</td><td>',$value).'</td></tr>';
            }
        }
        if ($html != '') $html = '<table>'.$html.'</table>';
    }
    return $html;
}

function build_table($array){
    $html = '';
     foreach( $array as $key=>$value){
        $html .= '<tr>';
        foreach($value as $key2=>$value2){
            $html .= '<td>' . htmlspecialchars($value2) . '</td>';
        }
        $html .= '</tr>';
    }
    return $html? '<table>' . $html . '</table>' : '';
}
