排序simplexml数组

问题描述

我有这个simplexml数组，我设法通过Google上的示例开始工作.现在我必须对数组进行排序.

I have this simplexml array which i managed to get working from examples on google. now i have to sort the array.

这就是我所拥有的.

$url = 'http://api.trademe.co.nz/v1/Member/2128687/Listings/All.xml';

$xml = simplexml_load_file($url);

foreach($xml->List->Listing as $list){
echo $list->EndDate;
echo '<br/>';
}

一切正常.我想按最接近结束日期的顺序对其进行排序.

everything works as it should like that. i want to sort it by closest to end date.

ive尝试了所有我能找到的示例，但我一直都没有白屏.

ive tried all the examples i can find and i just keep getting white screen of nothing.

请帮助！

推荐答案

function cmp($a, $b)
{
    $a = strtotime($a->EndDate);
    $b = strtotime($b->EndDate);
    if ($a == $b) 
    {
        return 0;
    }
    return ($a < $b) ? -1 : 1;
}

uasort($xml->List->Listing, 'cmp');
print_r($array);
