并且我想使用名为[noticia] 的键值对数组进行排序。我已经尝试了很多，但我未能在不更改其索引的情况下使用此键值进行排序。
我需要同时使用两个键值对数组进行排序，这意味着使用最近的 fecha（日期），还需要使用 noticia 对数组进行排序。我该怎么做？
【问题讨论】：
目前我正在使用这个函数对数组进行排序，但我从来没有得到我想要的结果，我不知道我使用的错误。function sorttitle($a, $b) if ($a- >noticia == $b->noticia) 返回 0；返回 ($a->noticia noticia) ？ 1：-1； uasort($this->items, 'sorttitle'); 这里是原始数组 [link]doceysumando.ddns.net:18080/icm-indra2/index.php/videos/videos/… 我想用 DESC 顺序对数组进行排序 此处为空的 [noticia] 值？ 父数组的名称？ 【参考方案1】：function cmp($a, $b)
return strcmp($a->count, $b->count);
usort($your_array, "cmp");
使用usort()
【讨论】：
什么是 $a 和 $b ？！ cmp 函数是如何使用 $a 和 $b 的？ @AfghanWiz，请阅读答案中提供的链接文档。 如果我想用 noticia 排序并用 fecha 排序意味着最近的在前.. 那我该怎么办？ 我需要一个简单的数组，最近的第一个，并且还按通知排序。你明白我的需要吗？我知道这有点令人困惑，但请帮助我 @ProgrammingStudent，是的，你是对的！ :)【参考方案2】：这使用uasort() 函数按 DESC 顺序按通知字段对数组进行排序：
function fn($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);
