我想更换按键[0] [1] [2] [3] [4] [5] [6]

的值为

$arraysecond = 

    Array
    (
        [0] => Monday
        [1] => Tuesday
        [2] => Wedneday
        [3] => Thursday
        [4] => Friday
        [5] => Saturday
        [6] => Sunday
    )

请帮忙。

Answer 1

您可以使用array_combine -

$new = array_combine($arraysecond, $arrayfirst);

$arraysecond的值将是$arrayfirst的键。

array_combine()

Answer 2

$arrayfirst = array(
        0 => '23:00-08:00',
        1 => '23:00-08:00',
        2 => '23:00-08:00',
        3 => '23:00-08:00',
        4 => '23:00-08:00',
        5 => '00:00-00:00',
        6 => '00:00-00:00',
    );

    $arraysecond = array(
        0 => 'Monday',
        1 => 'Tuesday',
        2 => 'Wedneday',
        3 => 'Thursday',
        4 => 'Friday',
        5 => 'Saturday',
        6 => 'Sunday',
    );

    $new = array_combine($arraysecond, $arrayfirst);

    echo '<pre>';
    print_r($new);
    echo '</pre>';

输出

Array
(
    [Monday] => 23:00-08:00
    [Tuesday] => 23:00-08:00
    [Wedneday] => 23:00-08:00
    [Thursday] => 23:00-08:00
    [Friday] => 23:00-08:00
    [Saturday] => 00:00-00:00
    [Sunday] => 00:00-00:00
)
