Question

我有一个像这样的数组

["2018-10-01","2018-10-15","Night Shift","20:00:00","06:00:00"],
["2018-10-16","2018-10-31","regular work schedule","09:00:00","18:00:00"],
["2018-11-01","2018-11-08","Night Shift","20:00:00","06:00:00"]

我想将两个日期放在同一数组中。

[["2018-10-01","2018-10-15"],"Night Shift","20:00:00","06:00:00"],
[["2018-10-16","2018-10-31"],"regular work schedule","09:00:00","18:00:00"],
[["2018-11-01","2018-11-08"],"Night Shift","20:00:00","06:00:00"]

我是php的新手，以及如何在php中做到这一点

Answer 1

要在数组（多维数组）中包含数组，您要做的就是在声明中指定数组。

$test = array(array("2018-10-01","2018-10-15"),"Night Shift","20:00:00","06:00:00")

因此要访问变量，例如获取第一个日期或第二个日期，您可以回显：

echo $test[0][0]; //first date
echo $test[0][1]; //second date
echo $test[1]; //the words, "Night Shift"

Answer 2

您可以迭代数组，并按以下方式操作前两个元素：

$arr =  array( ["2018-10-01","2018-10-15","Night Shift","20:00:00","06:00:00"],["2018-10-16","2018-10-31","regular work schedule","09:00:00","18:00:00"],["2018-11-01","2018-11-08","Night Shift","20:00:00","06:00:00"]);

foreach($arr as &$elem) {
    $a = array_shift($elem); // get the first date to var a and remove from elem
    $elem[0] = array($a, $elem[0]); // insert to index 0 array with both dates
}

echo print_r($arr);

这将输出：

Array (
    [0] => Array
        (
            [0] => Array
                (
                    [0] => 2018-10-01
                    [1] => 2018-10-15
                )

            [1] => Night Shift
            [2] => 20:00:00
            [3] => 06:00:00
        )

    [1] => Array
        (
      ....

将值从单维数组转换为多维数组
