合并多维数组中的数组

Question

我有一个像这样的动态数组，问题看起来很简单，但我没能解决。

[
  [
        "order_id" => "65", 
        "products" => [
           [
              "description" => "Test6", 
              "brand" => "ACL", 
              "code" => "303127005576", 
              "OriginalPrice" => "328.0000"
           ] 
        ] 
     ], 
  [
                 **"order_id" => "66",**  
                 "products" => [
                    [
                       "description" => "Test5", 
                       "brand" => "TEA", 
                       "code" => "3900055", 
                       "OriginalPrice" => "43.0000" 
                    ] 
                 ] 
              ], 
  [
                          **"order_id" => "66", **
                          "products" => [
                             [
                                "description" => "Te3st4", 
                                "brand" => "TEA", 
                                "code" => "3900056", 
                                "OriginalPrice" => "43.0000"
                             ] 
                          ] 
                     ]
                                                 
]; 

我想根据 **order_id ** 值合并多维数组内的数组以获得如下结果：

[
  [
        "order_id" => "65", 
        "products" => [
           [
              "description" => "test3", 
              "brand" => "ACL", 
              "code" => "303127005576", 
              "OriginalPrice" => "328.0000"
           ] 
        ] 
     ], 
  [
                 **"order_id" => "66",** 
                 "products" => [
                    [
                       "description" => "Test2", 
                       "brand" => "TEA", 
                       "code" => "3900055", 
                       "OriginalPrice" => "43.0000" 
                    ],
                    [
                      "description" => "Test1", 
                      "brand" => "TEA", 
                      "code" => "3900056", 
                      "OriginalPrice" => "43.0000"
                   ]
                 ] 
              ]
]; 

我尝试了不同的合并解决方案，但不幸的是对我不起作用

我认为应该有效

$productsTemp = [];
$ordersMerge = [];

foreach ($ordersGlobal as $actualOrder)
{
    if (key_exists($actualOrder["order_id"], $productsTemp))
    {
        $productsTemp[$actualOrder["order_id"]]["products"][] = $actualOrder["products"];
    }
    else
    {
        $productsTemp[$actualOrder["order_id"]]["products"] = $actualOrder["products"];
    }
}

$ordersMerge[] = $productsTemp;
