Question

我有一个阵列district，其中包含36个区，我正在取他们的总统和区域秘书。

$districts=$this->dashboard->get_districts();
foreach($districts AS $district)
        {

            $contacts=$this->dashboard->get_contacts($district["ID"]);

            $result=array_merge($result,$contacts);


        }

并加载视图：

$finalArray["result"]=$result;

        $this->load->view("admin/view_contacts.php",$finalArray);

所需数组 但我想要一个这种形状的数组，即键作为地区名称，以及带有联系方式的子数组

$testarray=array(
            "Attock"=>array(
                "president"=>"gulzar",
                "secretary"=>"musa"
            ),
            "Bahawalnagar"=>array(
                "president"=>"muzamil",
                "secretary"=>"tania"
            )
        );

Answer 1

您需要在$results数组中设置正确的密钥。为此，你需要这样的东西：

foreach($districts AS $district)
{
  $result[$district['name']] = $this->dashboard->get_contacts($district["ID"]);
  //                 ^^^^ this is of course a guess and depends on your column name
}

此外，假设您的get_contacts()方法进行数据库查询，执行JOIN并在一个数据库查询中获取组合的必要结果可能更有效。您仍然可以遍历结果以构建所需的输出数组。

Answer 2

$districts=$this->dashboard->get_districts();
$returnArray = array();
foreach($districts AS $district)
{
  $contacts=$this->dashboard->get_contacts($district["ID"]);
  $returnArray[$district['name']]['president'] = //Insert president value here.
  $returnArray[$district['name']]['secretary'] = //Insert secretary value here.
}
