从php数组中最常见的idtreatment

Question

我有一个数组，从查询中返回，向我显示某个时间段内的所有预订。我试图找到这个阵列中最常见的治疗方法。治疗在阵列中作为治疗。我怎么会开始搜索数组来找到最常见的idtreatment值？我尝试过使用

          $return = array();
        foreach ($treatment as $a) 
        {
           foreach ($treatment as $b) 
           {
               if ($a === $b) continue;
               $return = array_merge($return, array_intersect($a, $b));
           }
        } 

其中$ treatment是下面的数组，但它似乎只包含所有其他常见值，而不仅仅是查看iddreatment而只是考虑到这一点

Answer 1

如果您想要$treatment最常见的情况，请关闭idtreatment数组，您可以执行以下操作：

$idTreatments = [];

foreach ($treatment as $value) {

    $id = $value['idtreatment'];

    if (!isset($idTreatments[$id])) {
        $idTreatments[$id] = 0;
    }

    $idTreatments[$id]++;
}

arsort($idTreatments);

$commonTreatment = key($idTreatments);

如果您使用的是PHP 5.5+，则可以使用array_column和array_count_values代替foreach循环：

$idTreatments = array_count_values(array_column($treatment, 'idtreatment'));   

希望这有帮助！
