使用PHP计算多个总值的百分比

使用PHP计算多个总值的百分比,php,arrays,rounding,percentage,totals,Php,Arrays,Rounding,Percentage,Totals,我有一个多值数组 foreach($results as $row) { $count = $row['count']; $type = $row['type']; $array[$type][] = $count; } 当我将数组输出到表中时,它如下所示 Type Count AA 4 AE 59 AF 13 BB 44 BC 16 BD 36 我现在想要第三列的百分比,但我不知道如何实现 e

我有一个多值数组

foreach($results as $row) {
   $count = $row['count'];
   $type = $row['type'];
   $array[$type][] = $count;
}
当我将数组输出到表中时,它如下所示

 Type   Count
  AA      4
  AE     59
  AF     13
  BB     44
  BC     16
  BD     36
我现在想要第三列的百分比,但我不知道如何实现

e、 g.AA为5%,AE为39%等


我该怎么做?

我没有得到与您建议的相同的计算结果,但以下是我的方法:

$results=[
    ['type'=>'AA','count'=>4],
    ['type'=>'AE','count'=>59],
    ['type'=>'AF','count'=>13],
    ['type'=>'BB','count'=>44],
    ['type'=>'BC','count'=>16],
    ['type'=>'BD','count'=>36]
    ];
$total=array_sum(array_column($results,'count'));
foreach($results as $row) {
    $array[$row['type']]=[$row['count'],(int)round($row['count']/$total*100)];
    // or round($row['count']/$total*100).'%' <-- if you want the % sign
}
var_export($array);

您需要知道所有值的总和,然后只需
($count/$sum)*100
array (
  'AA' => 
  array (
    0 => 4,
    1 => 2,
  ),
  'AE' => 
  array (
    0 => 59,
    1 => 34,
  ),
  'AF' => 
  array (
    0 => 13,
    1 => 8,
  ),
  'BB' => 
  array (
    0 => 44,
    1 => 26,
  ),
  'BC' => 
  array (
    0 => 16,
    1 => 9,
  ),
  'BD' => 
  array (
    0 => 36,
    1 => 21,
  ),
)
