两个数组合并问题
Jun 23, 2016 pm 01:46 PM 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 ) ) ) )

数组2有问题，18：00，与 22：00的下标都是2，把22:00改为3
