怎么获取指定时间段的内容，并且对应好其他数组

  function myFunction($v) 
    {
	  $start='2013-09-23 10:48:33';
	  $end='2013-09-27 11:28:13';
    if ($v>=$start && $v<=$end)
        {
            return true;
        }
            return false;
    }
$t1=Array ( '0' => '南昌' ,'1' => '南昌' ,'2' => '赣州' ,'3' => '九江' ,'4' =>'赣州'  ,'5' => '九江') ;
$t2=Array ( '0' => '2013-09-24 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' );
    $t=array_filter($t2,"myFunction");
	
	foreach(array_keys($t) as $k) $t11[]=$t1[$k];
	$t22=array_values($t);
	print_r($t22);
	print_r($t11);
