これを回避できる方法はありますか(データベース内のディレクトリデータをループし、すべての子と子の子に対して同じデータを取得します...無限:

$directories = DB::queryOneColumn('id', "SELECT `id` FROM `data` WHERE `level` = '1' AND `batch` = %s", $lastBatchID);
foreach ($directories as $dir) {

$dirInfo = DB::query("SELECT `folder`, `size` FROM `data` WHERE `id` = $dir");
$size = intval($dirInfo[0]['size']) * 1024;
echo stripslashes($dirInfo[0]['folder']) . "  -Current:" . human_filesize($size) . "<br>";


$directories2 = DB::queryOneColumn('id', "SELECT `id` FROM `data` WHERE `parentID` = %s AND `batch` = %s", $dir, $lastBatchID);

foreach ($directories2 as $dir2) {

    $dirInfo = DB::query("SELECT `folder`, `size` FROM `data` WHERE `id` = $dir2");
    $size = intval($dirInfo[0]['size']) * 1024;
    echo "=>" . stripslashes($dirInfo[0]['folder']) . "  -Current:" . human_filesize($size) . "<br>";


    $directories3 = DB::queryOneColumn('id', "SELECT `id` FROM `data` WHERE `parentID` = %s AND `batch` = %s", $dir2, $lastBatchID);

    foreach ($directories3 as $dir3) {

        $dirInfo = DB::query("SELECT `folder`, `size` FROM `data` WHERE `id` = $dir3");
        $size = intval($dirInfo[0]['size']) * 1024;
        echo "=>=>" . stripslashes($dirInfo[0]['folder']) . "  -Current:" . human_filesize($size) . "<br>";


        $directories4 = DB::queryOneColumn('id', "SELECT `id` FROM `data` WHERE `parentID` = %s AND `batch` = %s", $dir3, $lastBatchID);

        foreach ($directories4 as $dir4) {

            $dirInfo = DB::query("SELECT `folder`, `size` FROM `data` WHERE `id` = $dir4");
            $size = intval($dirInfo[0]['size']) * 1024;
            echo "=>=>=>" . stripslashes($dirInfo[0]['folder']) . "  -Current:" . human_filesize($size) . "<br>";

            $directories5 = DB::queryOneColumn('id', "SELECT `id` FROM `data` WHERE `parentID` = %s AND `batch` = %s", $dir4, $lastBatchID);

            foreach ($directories5 as $dir5) {

                $dirInfo = DB::query("SELECT `folder`, `size` FROM `data` WHERE `id` = $dir5");
                $size = intval($dirInfo[0]['size']) * 1024;
                echo "=>=>=>=>" . stripslashes($dirInfo[0]['folder']) . "  -Current:" . human_filesize($size) . "<br>";
            }
        }
    }
}

}

基本的に、ディレクトリの x レベルのデータを取得しており、次のようにデータを表示するには各レベルのループが必要です。

C:\it\AD-Chris Integration -Current:49.70M

必要な深さのレベル数を持つ変数が利用可能です
