集群查询结果由2列设置，并创建关联数组的关联数组

Question

我有一个阵列

district

，其中包含36个地区，我在地区ID上找到了他们的总裁兼秘书。

$districts = $this->dashboard->get_districts();
foreach ($districts AS $district)
{
    $contacts = $this->dashboard->get_contacts($district["ID"]);
    $result = array_merge($result, $contacts);
}

视图的加载是：

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

既定的阵列 但是我想要一个形状的数组，即钥匙作为区名称，以及带有联系人详细信息的子阵列

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

您需要在

$results

Answer 1

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
}

也是，假设您的

get_contacts()

方法是一个数据库查询，则进行

JOIN

并在一个数据库查询中获得必要的结果可能更有效。您仍然可以在结果上循环以构建所需的输出数组。

$districts=$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.
}
