两个数组合并问题

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									 								)		 						)		 				)		 		)

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
