如何在PHP中对数组和数据进行排序？ 8个答案

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“得分”值对这类信息进行排序，我该怎么办？：

Array
(
 [0] => stdClass Object
    (
        [name] => Morts par DÃ©shydratation
        [score] => 4
        [id] => dwater
    )

 [1] => stdClass Object
    (
        [name] => RÃ©parations de chantiers
        [score] => 87
        [id] => brep
    )

 [2] => stdClass Object
    (
        [name] => Campeur tÃ©mÃ©raire
        [score] => 77
        [id] => camp
    )

 [3] => stdClass Object
    (
        [name] => DÃ©coration
        [score] => 112
        [id] => deco
    )
)

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

PS：这已经是PHP值，我已经使用过json_decode。*

Where $data looks like this:

$ data的数据如下：

Array
(
    [0] => stdClass Object
        (
            [name] => Morts par DÃƒÂ©shydratation
            [score] => 4
            [id] => dwater
        )

    [1] => stdClass Object
        (
            [name] => RÃƒÂ©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:

输出：

Array
(
    [0] => stdClass Object
        (
            [name] => DÃ©coration
            [score] => 112
            [id] => deco
        )

    [1] => stdClass Object
        (
            [name] => RÃ©parations de chantiers
            [score] => 87
            [id] => brep
        )

    [2] => stdClass Object
        (
            [name] => Campeur tÃ©mÃ©raire
            [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 DÃ©shydratation
            [score] => 4
            [id] => dwater
        )
