Question

我使用以下代码片段从数据库中获取记录：

if($pdo)
{
$stmt = $pdo->query('SELECT ID,Province,City,Position,Locale FROM jobs');
$result=$stmt->fetchAll(PDO::FETCH_ASSOC);
print("<pre>".print_r($result,true)."</pre>");
}

我正在获取阵列：

我想为每个循环检索值并在网站上显示：

Province name
     city name:
     position name1:
     position name 2:
province name
      city name:
      Position  name 3:
      Position  name 4:

我写过代码：

<?foreach($result as $key=>$val):?> 
    <div class='r-wr'>
        <h2 class="region-heading"><?=$key?></h2>
            <?foreach($val as $city=>$result):?>
            <div class='c-wr'>
                <h3 class="city-heading"><?=$city?></h3>
                        <?foreach($result as $pos_key=>$position):?>
                    <div class="pstn-btn" position-id="<?=$pos_key;?>"><?=$position;?></div><br>
                    <?endforeach;?>
                    </div>
            <?endforeach;?>
            </div>
    <?endforeach;?>

任何人都可以帮助我如何编写每个循环来获取记录值。

Answer 1

foreach（$ result as $ row）{    echo“省名”。$ row ['省']。“
;    echo“City Name”。$ row ['City']。“
;    echo“Position Name”。$ row ['Position']。“
; }

Answer 2

foreach($result as $key=>$val){
    $res[$val['Province']][$val['City']][$val['ID']] = $val['Position'];
}

输出结果为：

Array
(
    [BC] => Array
        (
            [Winnipeg] => Array
                (
                    [1] => Licensed Technician - Body Technician
                )

        )

    [Prairies] => Array
        (
            [Winnipeg] => Array
                (
                    [2] => Licensed Technician - Body Technician
                )

            [Edmonton] => Array
                (
                    [3] => Tire Technician
                )

        )

    [Ontario] => Array
        (
            [Regional Support Centre (Mississauga)] => Array
                (
                    [4] => Customer Service Representative
                    [5] => Payroll and Benefits Administrator
                )

            [Mississauga] => Array
                (
                    [6] => Shunt-Delivery Driver
                    [7] => Technician
                )

        )

我运行演示

var height = $(".height").text();

结果：

<?php

$result = array(
  array(
    'ID' => 1,
    'Province' => 'BC',
    'City' => 'Winnipeg',
    'Position' => 'Licensed Technician - Body Technician',
    'Locale' => 'en'
  ),
  array(
    'ID' => 2,
    'Province' => 'Prairies',
    'City' => 'Winnipeg',
    'Position' => 'Licensed Technician - Body Technician',
    'Locale' => 'en'
  ),
  array(
    'ID' => 3,
    'Province' => 'Prairies',
    'City' => 'Edmonton',
    'Position' => 'Tire Technician',
    'Locale' => 'en'
  ),
  array(
    'ID' => 4,
    'Province' => 'Ontario',
    'City' => 'Regional Support Centre (Mississauga)',
    'Position' => 'Payroll and Benefits Representative',
    'Locale' => 'en'
  ),
  array(
    'ID' => 5,
    'Province' => 'Ontario',
    'City' => 'Regional Support Centre (Mississauga)',
    'Position' => 'Payroll and Benefits Administrator',
    'Locale' => 'en'
  ),
  array(
    'ID' => 6,
    'Province' => 'Ontario',
    'City' => 'Mississauga',
    'Position' => 'Shunt-Delivery Driver',
    'Locale' => 'en'
  ),
  array(
    'ID' => 7,
    'Province' => 'Ontario',
    'City' => 'Mississauga',
    'Position' => 'Technician',
    'Locale' => 'en'
  )
);

$temp = array();
foreach ($result as $key => $value) {
    $temp[$value['Province']][$value['City']][] = $value['Position'];
}
print_r($temp);

因为我已经搞乱了PHP，但你可以使用array_reduce来构建一个基于省的新哈希，并在该键下嵌套匹配记录，这样可以更容易地迭代：< / p>

<?php
$data = [array(
'id' => 1,
'Province' => 'Ontario',
'Position' => 'Customer Service',
), array(
'id' => 2,
'Province' => 'Ontario',
'Position' => 'Customer Service II',
), array(
'id' => 3,
'Province' => 'Edmunton',
'Position' => 'Janitor',
), array(
'id' => 4,
'Province' => 'Edmunton',
'Position' => 'Tire Technician',
)];

$provincePositions = array_reduce($data, function($carry, $item) {
    if (array_key_exists($item['Province'], $carry)) {
        array_push($carry[$item['Province']], $item);
    } else {
        $carry[$item['Province']] = [$item];
    }
    return $carry;
}, []);

foreach($provincePositions as $province => $positions) {
    echo $province . "\n";
    foreach ($positions as $position) {
        echo "\t" . $position['Position'] . "\n";
    }
}

输出结果为：

Ontario
        Customer Service
        Customer Service II
Edmunton
        Janitor
        Tire Technician
