比如
$t1=Array ( [0] => 南昌 [1] => 南昌 [2] => 赣州 [3] => 九江 [4] =>赣州 [5] => 九江)
$t2=Array ( [0] => 2013-09-23 17:48:33 [1] => 2013-09-23 12:48:42 [2] => 2013-09-21 17:48:23 [3] => 2013-09-12 08:40:03 [4] => 2013-09-23 10:28:22 [5] => 2013-09-27 11:28:13 )
现在$t1和$t2 都是相同长度。而且他们还存在一个对应关系。那就是t1[0]和t2[0]。。t1[1]和t2[1].....t1[i]和t2[i]是相关联的,
我现在想实现不重复t1里面的value不重复。然后在和t2对应,如果有重复的,就保留t2里面时间最小的那个。
并且新的数组t22里面的的value是从小到大的顺序。
得到的结果我想是,
$t11=Array ( [0] => 九江 [1] => 赣州 [2] => 南昌 )
$t22=Array ( [0] => 2013-09-12 08:40:03 [1] => 2013-09-21 17:48:23 [2] => 2013-09-23 12:48:42 )
或者把t1,t2合并成一个二维数组更方便实现也可以,感谢。
