因此,我期待着用“fk_page_id”的形式将多维阵列分类如下。 是否有人要问。 我认为,我们是我必须研究的领域,但似乎像我能够找到任何具有我具体阵容结构的人。

Array
    (

    [0] => Array

        (
            [title] => subpage of subpage!
            [id] => 5
            [long_title] =>
            [fk_page_id] => 4                                
        )

    [1] => Array
        (
            [title] => about us subpage
            [id] => 4
            [long_title] => 
            [fk_page_id] => 2
        )

    [2] => Array
        (
            [title] => about us
            [id] => 2
            [long_title] => 
            [fk_page_id] => 1
        )

)
最佳回答

如果您重新使用PHP5.3+:

define(ASC,1);
define(DESC,-1);

function colsort($array,$col,$order=ASC) {
    usort(
        $array,
        function($a,$b) use($col,$order) {
            return strcmp($a[$col],$b[$col])*$order;
        }
    );
    return $array;
}

colsort($x, fk_page_id );
问题回答
function cmp($a, $b) {
    if($a[ fk_page_id ] == $b[ fk_page_id ]) {
        return 0;
    } else {
        return $a[ fk_page_id ] < $b[ fk_page_id ] ? -1 : 1;
    }
}

usort($yourarray,  cmp );
