PHP Array Sum 通过相同的键值对需要计算

Question

<?php

你好朋友，我正在尝试上面的代码，我希望费用应该由具有相同 3 个键值对的人计算。 例如，如果每个数组的 3 个键值相同，则仅计算这些费用金额。

如果我理解您的问题，则每次其他 3 列具有相同值时，您都需要对费用列求和。我稍微定制了你的代码，这样你就可以知道每个元素的总成本。

//Declaration...
$pre_pid = "";
$pre_encounter = "";
$pre_code = "";
$pre_fee = "";
$sum_charges = 0;
$sum_array = array();
$total_fees = 0;
/*Foreach loop*/

foreach($test_array as &$my_arr){

    $pre_pid = $my_arr['pid'];
    $pre_encounter = $my_arr['encounter'];
    $pre_code = $my_arr['code'];
    $pre_fee = $my_arr['fee'];
    $fee_ammount = $pre_fee;
    $duplicates_check = array();

    foreach($test_array as $value) {
        if($pre_pid == $value['pid'] && ($pre_encounter != $value['encounter'] || $pre_code != $value['code'])){

            $duplicate = false;

            foreach($duplicates_check as $duplicate_array) {
                if($duplicate_array == $value)
                    $duplicate =true;
            }
            if(!$duplicate) {
                $fee_ammount += $value['fee'];
                $duplicates_check[] = $value;
            }
        }
    }
    $my_arr['total_fee'] = $fee_ammount;

    if(!isset($sum_array[$my_arr['pid']])) {
        $sum_array[$my_arr['pid']] = $my_arr['total_fee'];
        echo 'pid => '.$my_arr['pid'].', total fees => '.$my_arr['total_fee'].'<br />';
        $total_fees += $my_arr['total_fee'];
    }
}

echo 'Total : '.$total_fees;
var_dump($sum_array);
