[0] => Array

[caseid] => 31

合并后，最终数组应该是这样显示：
[code=php]
$result=Array
(
[0] => Array
(
[time] => 8:00
[detail] => Array
(
[0] => Array
(
[caseid] => 31
[casename] => 张三
)
[1] => Array
(
[caseid] => 32
[casename] =>李四
)
[2] => Array
(
[caseid] => 33
[casename] => 王五
)
)
[detail2] => Array
(
[0] => Array
(
[caseid] => 41
[casename] => 刘备
)
)
)
[1] => Array
(
[time] => 12:00
[detail] => Array
(
[0] => Array
(
[caseid] => 32
[casename] => 李四
)
[1] => Array
(
[caseid] => 33
[casename] => 王五
)
)
[detail2] => Array
(
)
)
[2] => Array
(
[time] => 16:00
[detail] => Array
(
)
[detail2] => Array
(
[0] => Array
(
[caseid] => 42
[casename] => 张飞
)
[1] => Array
(
[caseid] => 43
[casename] => 赵云
)
)
)
[3] => Array
(
[time] => 18:00
[detail] => Array
(
[0] => Array
(
[caseid] => 31
[casename] => 张三
)
[1] => Array
(

)
[2] => Array
(

[casename] => 王五
)
)
[detail2] => Array
(
[0] => Array
(

)
)
)
[4] => Array
(

php 提供了丰富的函数
你应该自己动动手

数组2有问题，18：00，与 22：00的下标都是2，把22:00改为3
