如何在PHP中總結數組值？

Question

我有2數組變量我想總結數組並分成兩部分。請看看我的代碼 -

print_r($public); 

輸出 -

Array 
(
    [0] => 2 
    [1] => 3 
    [2] => 5 
    [3] => 2 
    [4] => 1 
    [5] => 32 
    [6] => 5 
    [7] => 20 
    [8] => 0 
    [9] => 0 
    [10] => 0 
    [11] => 0 
    [12] => 0 
    [13] => 0 
    [14] => 7 
    [15] => 0 
    [16] => 0 
    [17] => 0 
    [18] => 0 
    [19] => 0 
    [20] => 0 
    [21] => 0 
    [22] => 0 
    [23] => 0 
    [24] => 0 
    [25] => 0 
    [26] => 11 
    [27] => 0 
    [28] => 0 
    [29] => 0 
    [30] => 0 
) 



print_r($private); 

Array 
(
    [0] => 0 
    [1] => 1 
    [2] => 0 
    [3] => 0 
    [4] => 1 
    [5] => 0 
    [6] => 0 
    [7] => 3 
    [8] => 0 
    [9] => 0 
    [10] => 0 
    [11] => 0 
    [12] => 0 
    [13] => 0 
    [14] => 7 
    [15] => 0 
    [16] => 0 
    [17] => 0 
    [18] => 0 
    [19] => 0 
    [20] => 0 
    [21] => 0 
    [22] => 4 
    [23] => 0 
    [24] => 0 
    [25] => 0 
    [26] => 0 
    [27] => 0 
    [28] => 2 
    [29] => 0 
    [30] => 0 
) 

我的輸出應該是 -

$variable1=array_sum($public) + array_sum($private); //for First 15 days(array) 
$variable2 = array_sum($public) + array_sum($private); //For 16 to end of the array 

$public和$private是二陣列。包含May月份日期明智記錄。我想將數組值分解爲兩個分割部分。

第一 - 天 - 1-15（陣列0的總和到14）

第二 - 日 - 月的16端（陣列15的總和以結束陣列）

如何在一行代碼中將兩個變量分成兩個分隔部分？

Answer 1

您可以使用array_slice：

$first_part = array_sum(array_slice($public, 0, 15)); 
$second_part = array_sum(array_slice($public, 15, 16)); 

---

$first_part = array_sum(array_slice($public, 0, 15)) + array_sum(array_slice($private, 0, 15)); 
$second_part = array_sum(array_slice($public, 15, 16)) + array_sum(array_slice($private, 15, 16));
