PHP如何合并数组和创建键？

我正在做一个自定义的单消括号，它必须自动检查结果，并根据结果创建一轮。我可以成功地检查结果并将团队保存在阵列中以供下一轮使用，但我的问题是它创建了一个奇怪的阵列：

    foreach ($competitors as $competitor) {
                    $teams = array();

                    if ($competitor['scoreHome'] > $competitor['scoreAway']) {
                        $teams = array(array('home'=>$competitor['home']));
                    } 

                    if ($competitor['scoreHome'] < $competitor['scoreAway'] ) {
                        $teams = array(array('away'=>$competitor['away']));
                    }
    }               
                    print_r($teams);

我需要的是重新编制这个数组的索引，并生成

array\u chunk（$teams，2）

，这样我就可以将信息保存到数据库中，并再次执行此过程，直到整个比赛结束

我想要的输出：

    Array
    (
    [0] => Array
        (
            [0] => Array
                (
                    [teamName] => testis1
                )

            [1] => Array
                (
                    [teamName] => testis5
                )

            )

    [1] => Array
    (
        [0] => Array
            (
                [teamName] => wdefgr
            )

        [1] => Array
            (
                [teamName] => testis2
            )

    )

我该怎么做呢？

我相信你想做的事情是这样的：

$teams = array();
foreach ($competitors as $competitor) {

  $match = array();
  /* fill this match with the info you want, eg. */
  $match[] = array(array('home'=>$competitor['home']));
  $match[] = array(array('away'=>$competitor['away']));

  $team[] = $match;
}               
print_r($teams);

我省略了内部条件，因为它们与答案无关，但你必须做你必须做的事情来填写内部信息。

我对八达通的答案做了更多的修改（请看下面的评论），并对代码进行了调整，使其能够完美工作。八达通回答中的示例显示一个索引太多，因此我提出以下建议：

    foreach ($competitors as $competitor) {

        if ($competitor['scoreHome'] > $competitor['scoreAway']) {
            $match[] = array('home'=>$competitor['home']);
        } 

        if ($competitor['scoreHome'] < $competitor['scoreAway'] ) {
            $match[] = array('away'=>$competitor['away']);
        }
    }

    $matches = array_chunk($match, 2);
    print_r($matches);

你能准确地展示你的预期输出是什么样子吗？是的，我刚刚编辑了这个问题，领带呢？您选中

，并且

您的
$teams
值在每次迭代时都会被覆盖。不，在本次锦标赛中，平局不是选项
    foreach ($competitors as $competitor) {

        if ($competitor['scoreHome'] > $competitor['scoreAway']) {
            $match[] = array('home'=>$competitor['home']);
        } 

        if ($competitor['scoreHome'] < $competitor['scoreAway'] ) {
            $match[] = array('away'=>$competitor['away']);
        }
    }

    $matches = array_chunk($match, 2);
    print_r($matches);

    Array
    (
        [0] => Array
            (
                [0] => Array
                    (
                        [away] => testis5
                    )

                [1] => Array
                    (
                        [home] => wdefgr
                    )

        )

        [1] => Array
            (
                [0] => Array
                    (
                        [away] => testis4
                    )

                [1] => Array
                    (
                        [home] => team1
                    )

            )
