排序多维数组 [英] sorting a multi-dimensional array

问题描述

如果之前已经回答了这个问题，我真的很抱歉，但这是我的问题
我有这个:

I'm really sorry if this has been answered before, but here is my problem
I have this:

 array (size=256)
      0 =>
            array (size=2)<br>
                0 => string 'name_a'
                1 => string '2175'
      1 =>
            array (size=2)
                0 => string 'name_d'
                1 => string '1'
      2 =><
            array (size=2)
                0 => string 'name_c'
                1 => string '715'
      3 =>
            array (size=2)
                0 => string 'name_b'
                1 => string '5'

如果我为每个名称添加更多信息(例如时间值)，我希望能够按从最大到最小或/和名称的数字对其进行排序.它的数组很大(我认为超过400个)，我需要从上到下逐一显示它.如果有人有任何想法，我很想听听他们的想法！

And I want to be able to sort it by the number from most to least or/and name and if I add more info for each name such as time value. Its a huge array(over 400 I think) and I need to display it one by one, from top to bottom. If anyone have any ideas, I'd love to hear them!

推荐答案

使用 usort 就像这样:

Use usort like so:

function myComp($a, $b) {
    if($a[1] == $b[1]) {
        return 0;
    }

    return ($a[1] > $b[1]) ? -1 : 1;
}

usort($myArray, 'myComp');
