PHP阵列总和通过相同的键值对需要计算

Question

<?php 
error_reporting(E_ALL); 
$test_array = Array(Array

    "pid" => 1, 
    "encounter" => 20,

你好朋友我想上面的代码，我想要费用应该计算谁拥有相同的3键值对。 例如，如果每个数组3键值相同，则只计算这些费用数量。

如果我理解你的问题，你需要总结的费列每次3个其他列具有相同的值。我定制了一下你的代码，这样你就可以为你的每个元素提供总成本。

//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);
