多个排序以阵列 [英] Multiple sorts in an array

问题描述

我有以下数组：

Array
(
[0] => Array
    (
        [note] => test
        [year] => 2011
        [type] => football
    )

[1] => Array
    (
        [note] => test1
        [year] => 2010
        [type] => basket
    )

[2] => Array
    (
        [note] => test2
        [year] => 2012
        [type] => football
    )

[3] => Array
    (
        [note] => test3
        [year] => 2009
        [type] => basket
    )

[4] => Array
    (
        [note] => test4
        [year] => 2010
        [type] => football
    )

)

和我想首先根据按类型另一个数组排序是：

And I would like to first sort it according another array by type:

例如： $排序=阵列（'足球'，'篮子'）;

和事后的一年。

我怎么能这样做？

感谢。

所需的输出应该是：

Array
(
[2] => Array
    (
        [note] => test2
        [year] => 2012
        [type] => football
    )
[0] => Array
    (
        [note] => test
        [year] => 2011
        [type] => football
    )
[4] => Array
    (
        [note] => test4
        [year] => 2010
        [type] => football
    )

[1] => Array
    (
        [note] => test1
        [year] => 2010
        [type] => basket
    )

[3] => Array
    (
        [note] => test3
        [year] => 2009
        [type] => basket
    )

)

如果我们重置索引值，我不介意。

I do not mind if we reset the index values.

感谢。

推荐答案

使用 在array_multisort 。假设你的数组是 $改编：

foreach($arr as $key=>$row) {
    $type[$key] = $row['type'];
    $year[$key] = $row['year'];
}
array_multisort($type, SORT_ASC, $year, SORT_ASC, $arr);

要使用addictional指定数组类型顺序，你可以这样做：

To use an addictional array specifying type order, you could do:

$sortBy = array('football','basket');
foreach($arr as $key=>$row) {
    $type[$key] = array_search($row['type'],$sortBy);
    $year[$key] = $row['year'];
}
array_multisort($type, SORT_ASC, $year, SORT_ASC, $arr);
