基於php中的多個鍵值計算值

-1

我有一個result array在PHP中。我想根據多個關鍵值對數值進行計數。例如：基於php中的多個鍵值計算值

我想算屬於「fromcity」 =>拉合爾和「tocity」 =>薩希瓦爾

而且也同所有其他fromcity和tocity出發計數所有離境。

像聲明組一樣。

請幫助我。

我有以下結果數組在PHP中：

$result_array = array 
    (
     [0] => array

       "tocity" => "Buhawalpur" 
      )

請修改您的問題，以包括您試圖達到預期效果。 – Epodax

你必須自己來實現這一點。簡單地遍歷$result_array並計算你需要什麼：

$counter = 0; 
foreach($result_array as $item) { 
    if($item['fromcity'] == 'Lahore' and $item['tocity'] == 'Sahiwal') { 
    $counter++; 
    } 
} 

echo "My current count is " . $counter;

你可能想implment計數功能，將剛剛返回櫃檯。

感謝回覆@ivanka Todorova – Faysal

@Ivanka Todorova，如果我想統計所有的值，那麼我需要把這麼多的條件。這樣就不會滿足我的要求。我想統計所有城市的所有班次。我需要的結果數組是拉合爾To Sahiwal（10） – Faysal

對不起，我需要的結果數組是這樣的類型：lahore to sahiwal（8）;拉合爾到多（6）; multan to islamabad（7） – Faysal

如果你想基於fromcity和tocity組，可以執行以下操作：

$count = []; 
foreach($result_array as $element) { 
    $search = $element['fromcity']. '-'. $element['tocity']; 
    if(!isset($count[$search])) { 
     $count[$search] = 1; 
    } else { 
     $count[$search] += 1; 
    } 
} 

//Result: 
foreach($count as $name => $cnt) { 
echo $name.' - '. $cnt .PHP_EOL; 
}

編輯：現在必須正常工作。
