我想用一个名为[noticia]的键值对数组进行排序。我已经尝试了很多但是我没有在不改变其索引的情况下使用此键值进行排序。

我需要对具有两个键值的数组进行排序，同时表示最近的fecha（date）以及带有noticia的排序数组。我怎么能这样做？

2 个答案:

答案 0 :(得分：0)

function cmp($a, $b) {
  return strcmp($a->count, $b->count);
}
usort($your_array, "cmp");

使用usort()

答案 1 :(得分：0)

这使用uasort()函数在DESC顺序中按照noticia字段对数组进行排序：

function fn($a, $b) {
     if ($a['fetcha'] == $b['fetcha']) {
        if($a['noticia'] == $b['noticia']) {
           return 0;
        }
        return ($a['noticia'] > $b['noticia']) ? -1 : 1;
    }
    return ($a['fetcha'] > $b['fetcha']) ? -1 : 1;
}
uasort($arrayName, "fn");

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