Как не создать большой, если список в этой части моего кода?

Question

Я не хочу создавать большой список if для всех глав истории моего сайта.

если $ commentformname [$ a] равно номеру текущей главы, тогда я делаю массив $ commentonchapter1 [$ a], говорящий о том, что комментарий был вставлен в главу 1, главу 2 и т. д.

Так что, если комментарий был опубликован в главе 2, будет создан массив commentonchapter2. .

if ($sitecomments == true) {
    $c = 0;
    $i = 0;
    $z = 0;
    #defines the comment form name, name of who commented, the comment text and time (to be converted, example: 2020-04-09T15:53:07.580Za > 12:53 09/04/2020)
    while ($c <= $commentsnumb) {
        $commentformname[$z] = $comments[$i];
        $i++;

        $commenttername[$z] = $comments[$i];
        $i++;

        $commenttext[$z] = $comments[$i];
        $i++;

        $commenttime[$z] = $comments[$i];
        $i++;

        $c++;
        $z++;
    }

    #shows the text of the comments tab
    echo '<hr class="'.$sitehr2.'" />'."\n";
    echo $divzoomanim.'<'.$n.'><p></p><br /><b>'.$tabnames[7].': '.$orangespan.$commentsnormalnumb.$spanc.' '.$icons[12].'</b><br /><br /><p></p></'.$n.'>'.$divc.'<hr class="'.$sitehr.'" />'."\n";

    $i = 0;
    $z = 0;
    #converts the comment date and time
    #example
    #from 2020-04-09T15:53:07.580Za

        $z++;
    }
