以下两个数组并未在[2015]中合并，就像他们应该的那样。相反，它创建[2016]，就像在上一个例子中一样。
代码我使用：
$ merge = array_merge_recursive（$ array，$ current）;
第一个数组:( $ current）
Array
(
[Particulier] => Array
(
[Weekend] => Array
(
[2015] => Array
(
[06] => Array
(
[0] => Array
(
[id] => 111
[startDate] => 12-06-2015
[endDate] => 15-06-2015
[price] => 920
)
)
)
)
)
)
第二个数组：（$ array）
Array
(
[Particulier] => Array
(
[Weekend] => Array
(
[2015] => Array
(
[05] => Array
(
[0] => Array
(
[id] => 90
[startDate] => 01-05-2015
[endDate] => 04-05-2015
[price] => 920
)
[1] => Array
(
[id] => 91
[startDate] => 08-05-2015
[endDate] => 11-05-2015
[price] => 920
)
[2] => Array
(
[id] => 92
[startDate] => 15-05-2015
[endDate] => 18-05-2015
[price] => 920
)
)
[06] => Array
(
[0] => Array
(
[id] => 112
[startDate] => 19-06-2015
[endDate] => 22-06-2015
[price] => 920
)
)
)
)
[Midweek] => Array
(
[2015] => Array
(
[05] => Array
(
[0] => Array
(
[id] => 94
[startDate] => 11-05-2015
[endDate] => 15-05-2015
[price] => 1225
)
[1] => Array
(
[id] => 95
[startDate] => 18-05-2015
[endDate] => 22-05-2015
[price] => 1225
)
)
[06] => Array
(
[0] => Array
(
[id] => 118
[startDate] => 15-06-2015
[endDate] => 19-06-2015
[price] => 1225
)
)
)
)
)
[Clienten en patienten] => Array
(
[Weekend] => Array
(
[2015] => Array
(
[05] => Array
(
[0] => Array
(
[id] => 105
[startDate] => 01-05-2015
[endDate] => 04-05-2015
[price] => 645
)
)
)
)
)
)
当前结果：（$ merge）

[0] => Array
(
[id] => 112
[startDate] => 19-06-2015

)
[2016] => Array
(
[06] => Array

[startDate] => 12-06-2015
[endDate] => 15-06-2015
[price] => 920
)
)
)
)

如果需要任何其他信息，请询问！ 提前谢谢！
答案 0 :(得分：2)
根据您的描述，您必须使用关联数组（使用字符串索引，如＆＃34; 2015＆＃34;）而不是数字索引（如2015）。
我还建议使用唯一键作为事件的索引，并使用替代函数array_replace_recursive来阻止PHP创建任何嵌套数组（参见http://php.net/manual/en/function.array-replace-recursive.php）
