提问by Zenoo
I need to sort this kind of information by the "score" value in a PHP script, how can I do? :
我需要通过 PHP 脚本中的“分数”值对此类信息进行排序，我该怎么办？：
Array
(
[0] => stdClass Object
(
[name] => Morts par D??shydratation
[score] => 4
[id] => dwater
)
[1] => stdClass Object
(
[name] => R??parations de chantiers
[score] => 87
[id] => brep
)
[2] => stdClass Object
(
[name] => Campeur t??m??raire
[score] => 77
[id] => camp
)
[3] => stdClass Object
(
[name] => D??coration
[score] => 112
[id] => deco
)

哪里$data看起来像这样：
Array
(
[0] => stdClass Object

[name] => Morts par D????shydratation
[score] => 4
[id] => dwater
)
[1] => stdClass Object
(
[name] => R????parations de chantiers
[score] => 87
[id] => brep
)
[.] => ....
)
You can use usort()to sort the array :
您可以使用usort()对数组进行排序：
<?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);
?>
Outputs:
