Answer 1

您可以检查dice1值是否等于$ i，您可以添加某个使黑色为黑色的类。如果dice2值等于$ i，则相同。如果那么dice1等于$ i且dice2值等于$ j，请选择其他类别以使边框变为红色。

function chooseBorder($i,$j,$dice1,$dice2) {
    $class = "";
    if ($dice1 == $i && $dice2 == $j) {
        $class = "border-red";
        return $class;
    }

    if ($dice1 == $i || $dice2 == $j) {
        $class = "border-black";
        return $class;
    }

    return $class;
}


for ($i=0; $i < 6 ; $i++) {
    echo "<tr>";
    for ($j=0; $j < 6 ; $j++) {
        $class = chooseBorder($i,$j,$dice1,$dice2);
        echo "<td> <img class='icon cell color".mt_rand(1,4). " " . $class . "' src='img/icon".mt_rand(1,4).".svg ' </td>";
    }
    echo "</tr>";
}
