Question

我有一个如下所示的数组，在数组键“句点”下你有一个数组，其中包含四个数组，你可以看到它打开关闭，打开关闭，我希望它关闭打开，关闭打开，但是每对数组（open＆amp; close）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！多年来我一直在关注它，但我似乎无法让它正确迭代并保持这个顺序。

非常感谢任何帮助。谢谢。

array(1) {
  ["opening_hours"]=>
  array(1) {
    ["periods"]=>
    array(12) {

我想相信你的数组就像这样

$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
