Question

我试图在保持密钥名称的同时对密钥内的值进行求和打印出一系列值......

这是我拥有的数组：

Array ( 
    [Israel] => Array ( [0] => 3823 [1] => 1358 [2] => 496 [3] => 198 [4] => 134 [5] => 129 [6] => 107 [7] => 93 [8] => 91 [9] => 70 [10] => 60 [11] => 59 [12] => 54 [13] => 50 [15] => 35 [16] => 33 [17] => 33 [18] => 31 [19] => 28 [20] => 28 [24] => 19 [25] => 19 [27] => 18 [28] => 18 [29] => 15 [30] => 15 [31] => 14 [32] => 13 [33] => 13 [36] => 11 [37] => 10 [38] => 10 [39] => 10 [42] => 9 [45] => 7 [46] => 7 [51] => 6 [71] => 4 [72] => 4 [73] => 4 ) 
    [Palestine] => Array ( [14] => 48 ) 
    [Venezuela] => Array ( [21] => 21 [50] => 7 [64] => 5 [95] => 3 ) 
    [(not set)] => Array ( [22] => 20 ) 
    [United Kingdom] => Array ( [23] => 20 ) 
    [United States] => Array ( [26] => 19 [35] => 12 [40] => 10 [43] => 8 [47] => 7 [48] => 7 [49] => 7 [53] => 6 [54] => 6 [55] => 6 [56] => 6 [63] => 5 [76] => 4 [77] => 4 [90] => 3 [91] => 3 [92] => 3 [93] => 3 [94] => 3 ) 
    [Ecuador] => Array ( [34] => 12 [44] => 7 [83] => 3 ) 
    [Australia] => Array ( [41] => 9 [57] => 5 [97] => 2 ) 
    [Peru] => Array ( [52] => 6 ) 
    [China] => Array ( [58] => 5 ) 
    [El Salvador] => Array ( [59] => 5 ) 
    [Germany] => Array ( [60] => 5 [69] => 4 [85] => 3 [86] => 3 ) 
    [Paraguay] => Array ( [61] => 5 ) 
    [Poland] => Array ( [62] => 5 ) 
    [Armenia] => Array ( [65] => 4 ) 
    [Bolivia] => Array ( [66] => 4 [80] => 3 [81] => 3 [82] => 3 ) 
    [Canada] => Array ( [67] => 4 ) 
    [France] => Array ( [68] => 4 ) 
    [Guatemala] => Array ( [70] => 4 ) 
    [Nicaragua] => Array ( [74] => 4 ) 
    [Spain] => Array ( [75] => 4 [89] => 3 ) 
    [Uruguay] => Array ( [78] => 4 ) 
    [Argentina] => Array ( [79] => 3 ) 
    [Egypt] => Array ( [84] => 3 ) 
    [Italy] => Array ( [87] => 3 ) 
    [Nepal] => Array ( [88] => 3 ) 
    [Algeria] => Array ( [96] => 2 ) 
    [Belarus] => Array ( [98] => 2 ) 
    [Bulgaria] => Array ( [99] => 2 ) 
)

我正在寻找与此相似的结果：

isael：3400 巴勒斯坦：48 委内瑞拉：36

我尝试使用this但是它适用于我并且我不知道如何转换它

... ETC

Answer 1

使用array_sum()：

$output = array();
foreach ($array as $k => $a) {
  $output[$k] = array_sum($a);
}

Answer 2

怎么样：

foreach ($myArray as $k=>$subArray) {   
    $sumArray[$k] = 0;   
    foreach ($subArray as $id=>$value) {
       $sumArray[$k]+=$value;   
    }
}

因为$ k代表您所在的国家/地区，所以您将其子数组的所有值相加并将其存储在一个地图中，该地图的名称存储在$ k中。
