我有一个这样的数组输出;
[0] => Array
(
[fis_id] => 16149
[fis_urun] => 129
[fis_tarihi] => 2015-10-05 17:57:03
[kargo_tarih] => 2015-10-09 10:07:43
)
[1] => Array
(
[fis_id] => 16428
[fis_urun] => 128
[fis_tarihi] => 2015-10-07 18:45:31
[kargo_tarih] => 2015-10-09 09:21:18
)
[2] => Array
(
[fis_id] => 16544
[fis_urun] => 90
[fis_tarihi] => 2015-10-08 18:23:05
[kargo_tarih] => 2015-10-09 10:16:15
)
[3] => Array
(
[fis_id] => 16535
[fis_urun] => 91
[fis_tarihi] => 2015-10-08 17:44:34
[kargo_tarih] => 2015-10-09 09:16:39
)
[4] => Array
(
[fis_id] => 16527
[fis_urun] => 129
[fis_tarihi] => 2015-10-08 17:09:20
[kargo_tarih] => 2015-10-09 09:22:40
)
[5] => Array
(
[fis_id] => 16529
[fis_urun] => 90
[fis_tarihi] => 2015-10-08 17:11:49
[kargo_tarih] => 2015-10-09 09:19:00
)
在这个数组中，我想将数组结果分组为;
product=>90 count(2)
等
现在，我想重新排序我的阵列，按 fis_urun 数组键分组？那可能吗 ？如果是我该怎么办？
谢谢。

根据doc：
$ar1 = array(10, 100, 100, 0);
$ar2 = array(1, 3, 2, 4);
array_multisort($ar1, $ar2);
var_dump($ar1);
var_dump($ar2);
输出：
array(4) {
[0]=> int(0)
[1]=> int(10)
[2]=> int(100)
[3]=> int(100)
}
array(4) {
[0]=> int(4)
[1]=> int(1)
[2]=> int(2)
[3]=> int(3)
}
所以你需要做的是创建一个包含你的键的新数组，并根据新的一个顺序对你的第一个数组进行排序。
但首先，您必须重建当前阵列。
foreach($myMultiArray as $index => $values) {
$myGroupedArray[$values['fis_urun']][] = $values
}
这将使您的数组看起来像这样：
[129] => Array
(
[0] => Array
(
[fis_id] => 16149
[fis_urun] => 129
[fis_tarihi] => 2015-10-05 17:57:03
[kargo_tarih] => 2015-10-09 10:07:43
)
[1] => Array
(
[fis_id] => 16527
[fis_urun] => 129
[fis_tarihi] => 2015-10-08 17:09:20
[kargo_tarih] => 2015-10-09 09:22:40
)
)
[128] => Array
(
[0] => Array
(
[fis_id] => 16428
[fis_urun] => 128
[fis_tarihi] => 2015-10-07 18:45:31
[kargo_tarih] => 2015-10-09 09:21:18
)
)
[90] => Array
(
[0] => Array
(
[fis_id] => 16544
[fis_urun] => 90
[fis_tarihi] => 2015-10-08 18:23:05
[kargo_tarih] => 2015-10-09 10:16:15
)
[1] => Array
(
[fis_id] => 16529
[fis_urun] => 90
[fis_tarihi] => 2015-10-08 17:11:49
[kargo_tarih] => 2015-10-09 09:19:00
)
[91] => Array
(
[0] => Array
(
[fis_id] => 16535
[fis_urun] => 91
[fis_tarihi] => 2015-10-08 17:44:34
[kargo_tarih] => 2015-10-09 09:16:39
)
)
然后你必须对它进行排序:(使用数组多重排序或ksort，取决于您希望最终数组的第一级键，即（0,1,2,3）或（90 ，91,128,129）
foreach($myGroupedArray as $grouped_fis_urun => $values) {
$myFis_urun[] = $grouped_fis_urun;
}
array_multisort($myGroupedArray, $myFis_urun);
应该这样做......

这可能有效：
foreach ($your_array as $key => $val) {
$newArr[$value['fis_urun']] = $value
}
