Foreach并跳过特定的HTML

Question

我正在使用foreach来详细说明从网站上删除的一些值。它有效，但我有以下问题（我用屏幕以最好的方式解释我的问题）。

在第一个屏幕中，您可以看到Derry City - Limerick没有1 X 2赔率

但是当我得到这些值时，我的代码会以可用的第一个赔率填补空赔率，请参阅下面的屏幕：

这是HTML代码：

，至少，这是我的代码：

    $match_dates = $html->find("td[class=table-main__datetime]"); 
$titles = $html->find("a[class=in-match]"); // 1 per match
$odds = $html->find("td[class=table-matches__odds]/a"); // 2

function print_odd($odd) {
    if (array_key_exists('data-odd', $odd->attr)) {
        return $odd->attr['data-odd'];
    }

    return $odd->children(0)->children(0)->children(0)->attr['data-odd'];
}


$c=0; $b=0; $o=0; $z=0; // two counters
foreach ($titles as $match) {


    list($num1, $num2) = explode(':', $res->innertext); // <- explode   


    list($home, $away) = explode('-', $titles[$z++]->innertext); // <- explode
    list($date, $time) = explode('-', $match_dates[$o++]->innertext); // <- explode


$odd1 = print_odd($odds[$b++]);
$odd2 = print_odd($odds[$b++]);
$odd3 = print_odd($odds[$b++]);     


$home = strip_tags($home);
$away = strip_tags($away);
$uniquefield = $home . ' ' . $away;

            echo "<tr><td class='rtitle'>".
    //"<td class='last-cell'>".$match_dates[$o++]->innertext. "</td> " .
                "<td> ".$date.'</td><td> : </td><td>'.$time .  " / " .  

            "<td> ".$home.'</td><td> : </td><td>'.$away .  " / " .  

            "<td class='odds'>".$odd1 . ";" .
            "".$odd2  . ";" .
            "".$odd3  . "</td>" .
            "".$uniquefield."</td></tr><br/>";
