根據對象屬性對對象數組排序

Question

我有一個由對象組成的數組。

[ 
    { 
     "name" => "First", 
     "order" => 5 
    }, 
    { 
     "name" => "Second", 
     "order" => 3 
    }, 
    { 
     "name" => "Third", 
     "order" => 9 
] 

如何通過升序「order」值來訂購？

我應該得到：

[ 
    { 
     "name" => "Second", 
     "order" => 3 
    }, 
    { 
     "name" => "First", 
     "order" => 5 
    }, 
    { 
     "name" => "Third", 
     "order" => 9 
]; 

Answer 1

您應該能夠使用PHP usort()功能像這樣的數組：

usort($array, function($a, $b){return $a["order"]-$b["order"];}); 

或對象：

usort($array, function($a, $b){return $a->order-$b->order;}); 

這裏的PHP參考：usort()
