原数组：
$arr=array( [0] => Array ( [caseid] => 31 [name] => 张三 [shijian] => Array ( [0] => 8:00 [1] => 18:00 ) ) [1] => Array ( [caseid] => 32 [name] => 李四 [shijian] => Array ( [0] => 8:00 [1] => 12:00 [2] => 18:00 ) ) [2] => Array ( [caseid] => 33 [name] => 王五 [shijian] => Array ( [0] => 8:00 [1] => 12:00 [2] => 18:00 ) ))
我要将这个数组 重新组合，按照时间组合，组合完毕应该是这样的，搞了好久搞不出来。求助，谢谢
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 ) ) ))
