How I can sort news_published by descending order....I have tried with 'usort' but cant find the result properly can anyone suggest me?

推荐答案

试试这个：

$arr  = your array;
$sort = array();
foreach($arr as $k=>$v) {
    $sort['news_published'][$k] = $v['news_published'];
}

array_multisort($sort['news_published'], SORT_DESC, $arr);

echo "<pre>";
print_r($arr);
