从HTML表单关联数组构建PHP数组结构

我想从下面的html表单构建一个php数组结构。
我有下面的HTML表单

<!-- ROOM 1-->
 <div class="row">
       <div class="col-xs-4">
          <label>ADULTS</label>
          <div  class="selector">
             <select id='adults-1' name="rooms[0][adult]" class="full-width">
                <option value="1">1</option>
                <option value="2">2</option>
                <option value="3">3</option>
                <option value="4">4</option>
             </select>
          </div>
       </div>
       <div class="col-xs-4">
          <label>Copii</label>
          <div  class="selector">

如果您需要更多信息，请告诉我。

我认为变量$y是错误的。 请尝试以下代码：

$result = array();
if(!empty($_POST['rooms'])) {
    foreach($_POST['rooms'] as $k => $info) {
        for($y = 0; $y < $info['adult']; $y++) {
            $result[$k][]['paxType'] = 'Adult';
        }

        for($z = 0; $z < $info['child']; $z++) {
            $result[$k][]['paxType'] = 'Child';
        }
    }
}

整数用法：

/**
 * @param array      $array
 * @param int|string $position
 * @param mixed      $insert
 */
function array_insert(&$array, $position, $insert)
{
    if (is_int($position)) {
        array_splice($array, $position, 0, $insert);
    } else {
        $pos   = array_search($position, array_keys($array));
        $array = array_merge(
            array_slice($array, 0, $pos),
            $insert,
            array_slice($array, $pos)
        );
    }
}

$arr = ["one", "two", "three"];
array_insert(
    $arr,
    1,
    "on-half"
);
// ->
array (
  0 => 'one',
  1 => 'on-half',
  2 => 'two',
  3 => 'three',
)

$arr = [
    "name"  => [
        "type"      => "string",
        "maxlength" => "30",
    ],
    "email" => [
        "type"      => "email",
        "maxlength" => "150",
    ],
];

array_insert(
    $arr,
    "email",
    [
        "phone" => [
            "type"   => "string",
            "format" => "phone",
        ],
    ]
);
// ->
array (
  'name' =>
  array (
    'type' => 'string',
    'maxlength' => '30',
  ),
  'phone' =>
  array (
    'type' => 'string',
    'format' => 'phone',
  ),
  'email' =>
  array (
    'type' => 'email',
    'maxlength' => '150',
  ),
)

字符串用法：

/**
 * @param array      $array
 * @param int|string $position
 * @param mixed      $insert
 */
function array_insert(&$array, $position, $insert)
{
    if (is_int($position)) {
        array_splice($array, $position, 0, $insert);
    } else {
        $pos   = array_search($position, array_keys($array));
        $array = array_merge(
            array_slice($array, 0, $pos),
            $insert,
            array_slice($array, $pos)
        );
    }
}

$arr = ["one", "two", "three"];
array_insert(
    $arr,
    1,
    "on-half"
);
// ->
array (
  0 => 'one',
  1 => 'on-half',
  2 => 'two',
  3 => 'three',
)

$arr = [
    "name"  => [
        "type"      => "string",
        "maxlength" => "30",
    ],
    "email" => [
        "type"      => "email",
        "maxlength" => "150",
    ],
];

array_insert(
    $arr,
    "email",
    [
        "phone" => [
            "type"   => "string",
            "format" => "phone",
        ],
    ]
);
// ->
array (
  'name' =>
  array (
    'type' => 'string',
    'maxlength' => '30',
  ),
  'phone' =>
  array (
    'type' => 'string',
    'format' => 'phone',
  ),
  'email' =>
  array (
    'type' => 'email',
    'maxlength' => '150',
  ),
)

您还可以查看php.net手册：

尝试更改

for($y = 0; $y < $info['child']; $y++) {
    $result[$k][]['paxType'] = 'Child';
}

for（$y=0；$y<$info['child']；$y++）{
$result[$k]['paxType']='Child'；
}

到

for（$y=0；$y<$info['child']；$y++）{
$result[$k][]=array（'paxType'=>'Child'，'age'=>$info['age']）；
}

你想让所有的“孩子”都有相同的年龄吗？如中所示，如果用户选择房间[1][child]=3和房间[1][age]=5，是否希望所有3个“child”数组的“age”都设置为5？

我的代码也在工作，但我需要在数组结构中插入子年龄作为给定的示例。Thanks@em0tic0n我已经更新了我的答案，如果它有效，那么选择作为接受的答案。@Brianargh，如果是这样，孩子们应该有不同的年龄。那么房间[1][Child]中的3个“孩子”的年龄是多少？对于房间[1][age]，您只有一个下拉选项。
