Question

我有以下代码：

foreach ( $r2->{$id}->pages as $page ) {
    echo "<br>".$page->name.":<br>";
    foreach ( $page->slots as $slot ) {
        $id = $slot->runeId;
        $details = $result->$id->{'name'};
        echo $slot->runeSlotId.": ".$slot->runeId.": ".$details;
        echo "<br>";
    }
}

这会输出类似于：

我如何检查$slot->runeId的前一个foreach（）输出是否与此次输出的相同，然后在字符串末尾添加x1 ... x2 ... x3等？

示例：

1: 5245: Greater Mark of Attack Damage
2: 5245: Greater Mark of Attack Damage
3: 5245: Greater Mark of Attack Damage
4: 5245: Greater Mark of Attack Damage
5: 5245: Greater Mark of Attack Damage
6: 5245: Greater Mark of Attack Damage
7: 5245: Greater Mark of Attack Damage
8: 5245: Greater Mark of Attack Damage
9: 5245: Greater Mark of Attack Damage

->

1: 5245: Greater Mark of Attack Damage x9

Answer 1

试试这个

$lastId = 0;
$counter = 1;
foreach ( $r2->{$id}->pages as $page ) {
    echo "<br>".$page->name.":<br>";
    foreach ( $page->slots as $slot ) {
        $id = $slot->runeId;
        $details = $result->$id->{'name'};
        echo $slot->runeSlotId.": ".$slot->runeId.": ".$details.(($count==0)?(''):(' x'.$count));
        echo "<br>";

        if ($slot->runeId == $lastId) {
           $counter++;
        } else {
           $lastId = $slot->runeId;
           $counter = 1;
        }
    }
}

Answer 2

试试这个

foreach ( $r2->{$id}->pages as $page ) {

    $prev_id = "";
    $prev_count = 0;

    echo "<br>".$page->name.":<br>";
    foreach ( $page->slots as $slot ) {
        $id = $slot->runeId;
        $details = $result->$id->{'name'};

        if($prev_id!=$id)
        {
            if($prev_id!="")
            {
                echo " x".$prev_count;
                echo "<br/>";
                $prev_count = 0;
            }
            echo $slot->runeSlotId.": ".$slot->runeId.": ".$details;
        }
        $prev_count += 1;
        $prev_id = $id;
    }

    echo " x".$prev_count;
    echo "<br/>";
}

Answer 3

这可能有效：

foreach ( $r2->{$id}->pages as $page ) {
    echo "<br>".$page->name.":<br>";
    $tempSlot; $tempOut;
    $count = 0;
    foreach ( $page->slots as $slot ) {
        $id = $slot->runeId;
        $details = $result->$id->{'name'};
        $tempSlot =  $slot->runeSlotId.": ".$slot->runeId.": ".$details;
        if ($count == 0) {
            $tempOut == $tempSlot;
        }
        if ($tempSlot == $tempOut) {
            $count++;
        } else {
            echo $tempSlot;
            if ($count > 1) {
                echo " x".$count;
            }
            echo '<br>';
            $count = 0;
        }
    }
}

foreach（）检查以前是否是相同的ID
