代碼

$test_cnt = 0; 
test_encounter_pid = array(); 
foreach($provInnrArr as $dataDispArr){ 
    $test_encounter_pid['pid'] = $dataDispArr['pid']; 
    $test_encounter_pid['encounter'] = $dataDispArr['encounter']; 
    $test_encounter_pid['fee'] = $dataDispArr['fee']; 
    if (in_array($dataDispArr["encounter"], $test_encounter_pid)) { 
     $test_cnt += $dataDispArr['fee']; 
    } 
} 

朋友你好，以上是我的陣列我想求和所有陣列費鍵相關的值，只有當PID和遇到的是不同的 我越來越1,876.30合計但實際我需要是1,576.30 由於第二個數組值增加了300。我沒有得到如何解決它。

試試這個，

foreach($array as $val){ 

if($val['pid'] != "0"){ 
    if (!in_array($val['pid'], $temp_array)) 
    { 
    $temp_array[] = $val['pid']; 
    $total += $val['fee']; 
    } 
} 

echo $total;
