PHP Simple html dom kütüphanesini kullanarak ilgili tablodan veri çekiyorum. Ancak bir sorum var.

Tablolarda sınıf olmadığı için indeks numarasına göre veri alıyorum. Yılların günlerini almak istediğimde, "exaple: By 2021" td etiketi değil de th etiketi geldiğinde kaymalar oluyor.

Bu durumda hem yıllar hem de yıllar için gün sayısını nasıl alabilirim?

    // kodlarınız buraya eklenecek
    
    $total = 0;
 for($i = 7; $i <= 455; $i += 15){

        $year       = $html_base->find('td',$i)->plaintext;
        $days       = $html_base->find('td',$i + 2)->plaintext;

        $total += $html_base->find('td',$i + 3)->plaintext;
            if($year == "2020/11"){ break; } 

     }
