我有以下代码段：
foreach($data['matches'] as $record){
$matchday = $record['matchday'];
echo '<h4>Round'. $matchday .'</h4><br>'.$record['homeTeam']['name'].' - '.$record['awayTeam']['name'].'<br>';
}
它将循环遍历多维数组以显示比赛的所有日历匹配，matches是包含我正在使用的数组的键。我只需要提取每个赛季的比赛日一次，即可在标题<h4>等round 1，round 2等下显示每一轮的所有比赛。每个回合都有十个匹配项，如果我使用循环显示有关当前回合的信息，它将重复此信息，但是如果它们在同一回合下，则需要对它们进行分组。有可能实现这一目标吗？
这个想法是获得类似的东西：
Round 1
team 1 - team 2
team 3 - team 4
team 5 - team 6
Round 2
team 1 - team 2
team 3 - team 4
team 5 - team 6
ecc..
现在数据显示如下：
Round 1
team 1 - team 2
Round 1
team 3 - team 4
Round 1
team 5 - team 6
Round 2
team 1 - team 2
Round 2
team 3 - team 4
Round 2
team 5 - team 6
ecc..

答案 0 :(得分：0)
简单，增加一个变量，并检查当前回合和前一回合值是否相同。
类似下面的内容。
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="start"
android:layout_marginStart="5dp"
android:orientation="vertical"
android:weightSum=".9">
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.3"
android:text="@string/status_heading"
android:textSize="11sp" />
<ImageView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.3"
android:src="@drawable/ic_launcher_foreground" />
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.3"
android:text="test"
android:textSize="15sp" />
</LinearLayout>
其他解决方案是
使用键作为回合名称制作一个多维数组。
类似
$roundName = "";
foreach($data['matches'] as $record){
$matchday = $record['matchday'];
if($roundName != $matchday){
echo '<h4>Round'. $matchday .'</h4><br>';
}
echo $record['homeTeam']['name'].' - '.$record['awayTeam']['name'].'<br>';
$roundName = $record['matchday'];
}
