我需要通过PHP脚本中的得分"值对此类信息进行排序，我该怎么办? :

I need to sort this kind of information by the "score" value in a PHP script, how can I do? :

Array ( [0] => stdClass Object ( [name] => Morts par Déshydratation [score] => 4 [id] => dwater ) [1] => stdClass Object ( [name] => Réparations de chantiers [score] => 87 [id] => brep ) [2] => stdClass Object ( [name] => Campeur téméraire [score] => 77 [id] => camp ) [3] => stdClass Object ( [name] => Décoration [score] => 112 [id] => deco ) )

PS:这已经在一个PHP值中，我已经使用了json_decode.*

PS : This is already in a PHP value, I already used json_decode.*

推荐答案

其中$data看起来像这样:

Array ( [0] => stdClass Object ( [name] => Morts par Déshydratation [score] => 4 [id] => dwater ) [1] => stdClass Object ( [name] => Réparations de chantiers [score] => 87 [id] => brep ) [.] => .... )

您可以使用usort()对数组进行排序:

You can use usort() to sort the array :

<?php usort($data, function($a, $b) { //Sort the array using a user defined function return $a->score > $b->score ? -1 : 1; //Compare the scores }); print_r($data); ?>

输出:

Array ( [0] => stdClass Object ( [name] => Décoration [score] => 112 [id] => deco ) [1] => stdClass Object ( [name] => Réparations de chantiers [score] => 87 [id] => brep ) [2] => stdClass Object ( [name] => Campeur téméraire [score] => 77 [id] => camp ) [3] => stdClass Object ( [name] => Drogues [score] => 49 [id] => drug ) [4] => stdClass Object ( [name] => Ouverture de porte [score] => 11 [id] => door ) [5] => stdClass Object ( [name] => Morts par Déshydratation [score] => 4 [id] => dwater ) )
