PHP多维数组排序array_reverse无法正常工作? [英] PHP Multidimensional Array Sort array_reverse not working?

问题描述

我有一个 Multidimensional 数组，我正努力按照日期正确排序.

I have a Multidimensional array that I am trying feverishly to properly sort by the date.

到目前为止，我已经得到:

So far I've got:

usort($respArr, function($a, $b){
        $t1 = strtotime($a['PublishDate']);
        $t2 = strtotime($b['PublishDate']);
        return $t1 - $t2;
    });

array_reverse($respArr);
echo '<pre>';
print_r($respArr);
echo '</pre>';
echo '<hr />';

以下是上面的一些输出:

Here's some of the output from the above:

但是，正如您在上面所说的，数组不会反转. 有人可以帮我吗?
它向我展示了该数组确实按'PublishDate'排序，但是顺序相反.

However, the array is not reversed, as you can tell above. Can anyone help me with this?
It's showing me that the array is indeed sorted by the 'PublishDate', however, in the reverse order that I need it in.

推荐答案

实际的问题是您没有将array_reverse的结果分配给任何东西

The actual problem is you're not assigning the result of array_reverse to anything

// change this
array_reverse($respArr);

// to this
$respArr = array_reverse($respArr);
