我有两个具有共同索引的数组（教堂和办公室）。我需要将第一个数组的总数“合并”到第二个数组中以获得所需的输出（见双线下方）。我不确定如何使用 array_merge() 来做到这一点。任何帮助将不胜感激！

Array
(
    [church] => Array
        (
            [total] => 77
        )

    [office] => Array
        (
            [total] => 202
        )

)

Array
(
    [church] => Array
        (

            [name] => Array
                (
                    [0] => Bill
                    [1] => Sally
                )

            [addr] => Array
                (
                    [0] => Address Same as Billing
                    [1] => Address Same as Billing
                )

            [message] => Array
                (
                    [0] => 
                    [1] => 
                )

            [amount] => Array
                (

                    [1] => 50

        )

    [office] => Array
        (

            [name] => Array

                    [1] => Ruth
                )

                    [1] => Address Same as Billing
                )

            [message] => Array
                (
                    [0] => 
                    [1] => 
                )

            [amount] => Array
                (
                    [0] => 100
                    [1] => 100

【解决方案1】：

试试这样的：

$a = array('教堂' => array('total' => 5), 'office' => array('total' => 10));
$b = array('church' => array('name' => 'church'), 'office' => array('name' => 'office'));

foreach ( $b as $key => $value ) {
$b[$key] = array_merge($a[$key], $b[$key]);
}
