仅获得最高值[重复]

Question

我有这个foreach循环，我只想获取并显示最大值为buildings的数组

这是我的循环

$this->TaTarVillages = array();
foreach ($this->GetTaTaRVillages() as $value) {
    $this->TaTarVillages[] = array(
        'id' => $value['id'],
        'player_id' => $value['player_id'],
        'player_name' => $value['player_name'],
        'village_name' => $value['village_name'],
        'alliance_id' => $value['alliance_id'],
        'alliance_name' => $value['alliance_name'],
        'buildings' => $this->getWonderLandLevel($value['buildings'])
    );
}

使用 PHP 7

如果您只需要最大的数组，则不需要数组。每次循环，检查当前值是否大于你目前得到的最大值，如果是则替换它。

$largestVillage = $this->GetTaTaRVillages();
$largestVillage['buildings'] = $this->getWonderLandLevel($largestVillage['buildings']);
foreach ($this->GetTaTaRVillages() as $value) {
    $buildings = $this->getWonderLandLevel($value['buildings']);
    if ($buildings > $largestVillage['buildings']) {
        $largestVillage = $value;
        $largestVillage['buildings'] = $huildings;
    }
}
