Question

我有一个数组循环：

数组函数：

$truckTypesArray = array( 

                            "1" => "03 m3",
                            "2" => "05 m3",
                            "3" => "08 m3",
                            "4" => "10 m3",
                            "5" => "12 m3",
                            "6" => "14 m3",
                            "7" => "20 m3",
                            "8" => "20 m3 Hayon",

                            );


function getTruckTypes($truckTypesArray, $id)
{
    return $truckTypesArray[$id];
}

循环代码：

while($fetchPresentTruckTypes = mysql_fetch_array($getTruckTypeQuery))
{
    $createTruckTypeArray[]   = getTruckTypes($truckTypesArray, $fetchPresentTruckTypes['truckTypeId']);                    

}

$allTructTypes  = implode(",",$createTruckTypeArray);

现在它生成这个输出很好：

20 m3, 03 m3, 20 m3, 10 m3, 20 m3,

我希望它看起来像这样：

20 m3 = 3,
03 m3 = 1,
10 m3 = 1

Answer 1

使用this。它为您计算数组并返回您需要的数据。

Answer 2

function createTruck($createTruckTypeArray){
  $result = array();
  foreach($createTruckTypeArray as $val){
     $result[$val] = array_count_values($val);
  }
  return $result;
}

此函数返回一个这样的数组

array(
  '20 m3' => 3,
  '03 m3' => 1,
  '10 m3' => 1 
);

这会破坏你的结果。不要这样，请检查

implode(', ', array_map(function ($v, $k) { return $k . '=' . $v; }, $result, array_keys($result)));

在php数组中显示重复内容的计数器
