两个数组合并问题
本帖最后由 bluezsh 于 2014-10-16 16:25:27 编辑
数组1:

$arr1=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
 
)
 
)
 
)
 
[1] => Array
(
[time] => 12:00
[detail] => Array
(
[0] => Array
(
[caseid] => 32
[casename] => 李四 
)
[1] => Array
(
[caseid] => 33
[casename] => 王五 
)
 
)
 
)
 
[2] => Array
(
[time] => 18:00
[detail] => Array
(
[0] => Array
(
[caseid] => 31
[casename] => 张三
 
)
[1] => Array
(
[caseid] => 32
[casename] => 李四
 
)
[2] => Array
(
[caseid] => 33
[casename] => 王五
 
)
 
)
 
)
 
)


数组2

$arr2=Array
(
[0] => Array
(
[time] => 8:00
[detail2] => Array
(
[0] => Array
(
[caseid] => 41
[casename] => 刘备
 
)

)
 
)
 
[1] => Array
(
[time] => 16:00
[detail2] => Array
(
[0] => Array
(
[caseid] => 42
[casename] => 张飞 
)
[1] => Array
(
[caseid] => 43
[casename] => 赵云 
)
 
)
 
)
 
[2] => Array
(
[time] => 18:00
[detail2] => Array
(
[0] => Array
(
[caseid] => 43
[casename] => 赵云
 
)
 
)
 
)
[2] => Array
(
[time] => 22:00
[detail2] => Array
(
[0] => Array
(
[caseid] => 45
[casename] => 貂蝉
 
)
 
)
 
)
 
)

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
(
[caseid] => 32
[casename] => 李四
 
)
[2] => Array
(
[caseid] => 33
[casename] => 王五
 
)
 
)
[detail2] => Array
(
[0] => Array
(
[caseid] => 43
[casename] => 赵云
 
)
 
)
 
)
[4] => Array
(
[time] => 22:00
[detail] => Array
(

)
[detail2] => Array
(
[0] => Array
(
[caseid] => 45
[casename] => 貂蝉
 
)
 
)
 
)
 
)

php 提供了丰富的函数
你应该自己动动手
------解决思路----------------------
数组2有问题,18:00,与 22:00的下标都是2,把22:00改为3
