php数组循环合并的问题！

有这样的很多的数组，

Array('date' => 2011-11-30,'week' => 周三001);
Array('date' => 2011-11-30,'week' => 周三002);
Array('date' => 2011-11-30,'week' => 周三003);
Array('date' => 2011-12-01,'week' => 周四001);
Array('date' => 2011-12-01,'week' => 周四002);
Array('date' => 2011-12-01,'week' => 周四003);
Array('date' => 2011-12-02''week' => 周五001);
Array('date' => 2011-12-02,'week' => 周五002);
Array('date' => 2011-12-02,'week' => 周五003);
Array('date' => 2011-12-03,'week' => 周六001);
Array('date' => 2011-12-03,'week' => 周六002);
..........
合并成类似这样数组
$weekDate = arr(Array('date' => 2011-11-30,'week' => 星期三),Array('date' => 2011-12-01,'week' => 星期四),Array('date' => 2011-12-02,'week' => 星期五),Array('date' => 2011-12-03,'week' => 星期六))

Answer 1

$all_arr = array(
Array('date' => '2011-11-30','week' => '周三001'),
Array('date' => '2011-11-30','week' => '周三002'),
Array('date' => '2011-11-30','week' => '周三003'),
Array('date' => '2011-12-01','week' => '周四001'),
Array('date' => '2011-12-01','week' => '周四002'),
Array('date' => '2011-12-01','week' => '周四003'),
Array('date' => '2011-12-02','week' => '周五001'),
Array('date' => '2011-12-02','week' => '周五002'),
Array('date' => '2011-12-02','week' => '周五003'),
Array('date' => '2011-12-03','week' => '周六001'),
Array('date' => '2011-12-03','week' => '周六002'),
);

$weekDate[] = array('date' => $all_arr[0]['date'],'week' => substr($all_arr[$i+1]['week'], 0, -3));
for($i = 0; $i < count($all_arr) -1; $i++ )
{
if($all_arr[$i]['date'] != $all_arr[$i+1]['date'])
{
$weekDate[] = array('date' => $all_arr[$i+1]['date'],'week' => substr($all_arr[$i+1]['week'], 0, -3));
}
}

但是那些数组都是单个的啊，怎么样把它们放到一个大数组里面呢？

追答

楼主自己去看看 数组函数吧.
都已经写成这样了还看不懂 手册有木有啊

追问

您说的是array_merge() 这个函数么？但是貌似不好使耶！

追答

如果实在不会 最简单的写法
$all_arr[] = Array('date' => '2011-11-30','week' => '周三001');
$all_arr[] = Array('date' => '2011-11-30','week' => '周三002');
...

追问

嗯，谢谢，还有个小问题啊，怎么把 周三001 这样的 换成 星期这样呢？好像还是要循环，那是个二维数组！

追答

$weekDate 再循环下也是可以的 如果不循环就修改下

$weekDate[] = array('date' => $all_arr[$i+1]['date'],'week' =>str_replace('周' ,'星期',substr($all_arr[$i+1]['week'], 0, -3)));
for($i = 0; $i $all_arr[$i+1]['date'],'week' =>str_replace('周' ,'星期',substr($all_arr[$i+1]['week'], 0, -3)));
}
}
