php - 数组中第一对数组的翻转顺序

Question

我有一个如下所示的数组，在数组键“句点”下，您有一个包含四个数组的数组，您可以在其中看到它打开关闭，打开关闭，我希望它关闭打开，关闭打开，但是每对数组（打开和关闭）仍然需要以父数组格式保留它们的顺序。我真的希望这是有道理的！我一直在努力解决这个问题，但我似乎无法让它正确迭代并保持该顺序。

任何帮助都会非常感激。谢谢你。

array(1) {

  array(1) {

我想相信你的阵列是这样的

$array = array(
        "opening_hours" => array(
                "periods" => array(
                        0 => array("open" => array("day" => "1","time" => "0730")),
                        1 => array("close" => array("day" => "1","time" => "1200")),
                        2 => array("open" => array("day" => "1","time" => "1600")),
                        3 => array("close" => array("day" => "1","time" => "2345")),
                        4 => array("open" => array("day" => "2","time" => "0745")),
                        5 => array("close" => array("day" => "2","time" => "1200")),
                        6 => array("open" => array("day" => "2","time" => "1600")),
                        7 => array("close" => array("day" => "2","time" => "2345")),
                        8 => array("open" => array("day" => "3","time" => "0800")),
                        9 => array("close" => array("day" => "3","time" => "1200")),
                        10 => array("open" => array("day" => "3","time" => "1600")),
                        11 => array("close" => array("day" => "3","time" => "2345")))));

交换位置

$final = array();
$total = count($array['opening_hours']['periods']);

for($i = 0; $i < $total; $i += 2) {

    if (isset($array['opening_hours']['periods'][$i + 1])) {
        $final[] = $array['opening_hours']['periods'][$i + 1];
    }

    $final[] = $array['opening_hours']['periods'][$i];
}

var_dump($final);

输出
