如何从目录和CSV文件创建动态表

Question

我需要创建一个表，其第一列是从目录中的子目录名填充的，其余是来自CSV文件。 这必须是动态表，并且必须从代码中添加表头。 我的代码出了什么问题？

我是一个绝对的初学者。 所以，请忽略我的愚蠢。

$dir = 'D:\workspace';
$dirlist = preg_grep('/^([^.])/', scandir($dir)); 
$row = 1;
if (($handle = fopen("D:\workspace\demo\database.csv", "r")) !== FALSE) {

echo "<table border='1' style='border-collapse: collapse;border-color: silver;'>";

while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
    $num = count($data);
    if ($row == 1) {
        echo '<thead><tr>';
    }else{
        echo '<tr>';
    }

    for ($c=0; $c < $num; $c++) {

        if(empty($data[$c])) {
            $value = "&nbsp;";
        }else{
            $value = $data[$c];

        }
        if ($row == 1) {
            echo '<th>'.$value.'</th>';
        }else{
            foreach ($dirlist as $rowdirectory)
            {
                echo '<td>' . $rowdirectory . '</td>';
                echo '<td>'.$value.'</td>';

            }
        }

    }

    if ($row == 1) {
        echo '</tr></thead><tbody>';
    }else{
        echo '</tr>';
    }
    $row++;
}

echo '</tbody></table>';
fclose($handle);
}
