两个数组合并有关问题

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

数组2有问题，18：00，与 22：00的下标都是2，把22:00改为3
