Php 根据某个值对数组进行排序和排列

我有一个这样的数组

 [Defense] => Array
    (
        [0] => stdClass Object
            (
                [id] => 1
                [position] => G 
                [point] => 1.6

            )
        [1] => stdClass Object
            (
                [id] => 1
                [position] => F 
                [point] => 2.7
            )


        [2] => stdClass Object
            (
                [id] => 1
                [position] => C 
                [point] => 1.4
            )
        [3] => stdClass Object
            (
                [id] => 2
                [position] => C 
                [point] => 1.7
            )

        [4] => stdClass Object
            (
                [id] => 2
                [position] => D 
                [point] => 1.1
            )
        [5] => stdClass Object
            (
                [id] => 1
                [position] => F 
                [point] => 1.7
            ) 

        [6] => stdClass Object
            (
                [id] => 1
                [position] => G 
                [point] => 1.6

            )

        [7] => stdClass Object
            (
                [id] => 1
                [position] => G 
                [point] => 1.8

            )
       [8] => stdClass Object
        (
                [id] => 2
                [position] => D
                [point] => 1.5
        )   
  )

我想根据

PHP

中的点

降序对数组进行排序。此外，所有位置都是按顺序排列的（全部
G
比全部
F
依次类推）
像这样：

  [Defense] => Array
        (
            [0] => stdClass Object
                (
                    [id] => 1
                    [position] => G 
                    [point] => 1.8

                )
             [1] => stdClass Object
                (
                    [id] => 1
                    [position] => G 
                    [point] => 1.6

                )
            [2] => stdClass Object
                (
                    [id] => 1
                    [position] => G 
                    [point] => 1.6

                )   
            [3] => stdClass Object
                (
                    [id] => 1
                    [position] => F 
                    [point] => 2.7
                )
            [4] => stdClass Object
                (
                    [id] => 1
                    [position] => F 
                    [point] => 1.7
                )

            [5] => stdClass Object
                (
                    [id] => 1
                    [position] => C 
                    [point] => 1.7
                )
            [6] => stdClass Object
                (
                    [id] => 2
                    [position] => C 
                    [point] => 1.4 
                )
            [7] => stdClass Object
                (
                    [id] => 2
                    [position] => D
                    [point] => 1.5
                )
            [8] => stdClass Object
                (
                    [id] => 2
                    [position] => D 
                    [point] => 1.1
                )

      )

有什么帮助吗？
使用usort（）函数对数组进行排序，如下所示

usort($array,function($a,$b){
if($a->position == $b->position )
    return $a->point < $b->point;
else
    return $a->position < $b->position;
});
var_dump($array);

usort（$array，function（$a，$b）{
如果（$a->position==$b->position）
返回$a->point<$b->point；
其他的
返回$a->position<$b->position；
});
变量转储（$数组）；
我想说看看phps数组排序函数：
usort（）
或
uasort（）
。构建排序算法的逻辑或使用内置数组排序函数。将数组“point或position”变量传递到排序函数中，它们将被相应地排序。感谢各位的回复。@sam您发送的代码是按位置排序的，但不是根据“point”进行排序我想根据点“descending”进行排序运行我编写的上述函数，它首先检查点是否相等，它使用position进行排序，否则它使用point进行排序，这是默认情况，我建议您在php脚本中运行它，我已经运行了它并显示了完美的结果。我希望首先根据位置进行排序，然后对于这些位置，点将按DESC顺序排序。我希望这是有意义的
