Foreach and skip specific HTML - php

Question

I am using a foreach to elaborate some values scraped from a web site. It works but I have the follow problem (I put screens to explain my problem in the best way).
In the first screen, you can see that Derry City - Limerick doesn't have 1 X 2 odds
But when I get that values, my code fill empty odds with the first odds available, see the screen below:
This is the HTML code:
<table class="table-main js-tablebanner-t js-tablebanner-ntb">
<tr><th class="h-text-left" colspan="2">2. Round</th><th> </th><th class="table-main__bs">B's</th><th class="h-text-center">1</th><th class="h-text-center">X</th><th class="h-text-center">2</th></tr>
<tr>
<td class="table-main__datetime">21.03.2017 20:45</td>
<td class="h-text-left"><span>Derry City</span> - <span>Limerick</span></td>
<td class="h-text-right">
<ul class="list-tags"><li class="list-tags__item"><i class="icon icon__stream"></i><div class="list-tags__window list-tags__window--streams"><ul class="list-tags__window__in">
<li>Live streams</li>
<li>bwin</li>
<li>Sportingbet</li>
</ul></div></li></ul>
</td>
<td class="table-main__bs"> </td>
<td class="table-matches__odds" data-oid=""> </td>
<td class="table-matches__odds" data-oid=""> </td>
<td class="table-matches__odds" data-oid=""> </td>
</tr>
<tr><th class="h-text-left" colspan="2">5. Round</th><th> </th><th class="table-main__bs">B's</th><th class="h-text-center">1</th><th class="h-text-center">X</th><th class="h-text-center">2</th></tr>
<tr>
<td class="table-main__datetime">18.03.2017 15:00</td>
<td class="h-text-left"><span>Limerick</span> - <span>Finn Harps</span></td>
<td class="table-matches__odds" data-oid="2kou5xv464x0x5uaff"></td>
<td class="table-matches__odds" data-oid="2kou5xv498x0x0"></td>
<td class="table-matches__odds" data-oid="2kou5xv464x0x5uafg"></td>
</tr>
<tr>
<td class="table-main__datetime">18.03.2017 16:00</td>
<td class="h-text-left"><span>Derry City</span> - <span>Drogheda</span></td>
<td class="table-main__bs">23</td>
<td class="table-matches__odds" data-oid="2kp2nxv464x0x5uaoj"></td>
<td class="table-matches__odds" data-oid="2kp2nxv498x0x0"></td>
<td class="table-matches__odds" data-oid="2kp2nxv464x0x5uaok"></td>
</tr>
and, at least, this is my code:
$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/>";
