php - 如何在使用 array_chunk 时保留原始的唯一数组键？

Question

我有一个对象数组，每个对象都有一个唯一的随机 ID。

111 => 
    object(stdClass)[452]
      public 'Description' => string 'Description here...' (length=728)       
      public 'Name' => string 'Shirt' (length=18)
      public 'Price' => float 36.56

222 => 
    object(stdClass)[452]
      public 'Description' => string 'Description here...' (length=728)       
      public 'Name' => string 'Pants' (length=18)
      public 'Price' => float 36.56

333 => 
    object(stdClass)[452]
      public 'Description' => string 'Description here...' (length=728)       
      public 'Name' => string 'Dress' (length=18)
      public 'Price' => float 36.56

444 => 
    object(stdClass)[452]
      public 'Description' => string 'Description here...' (length=728)       
      public 'Name' => string 'Dress' (length=18)
      public 'Price' => float 36.56

...

我的目标是将我的键控对象数组拆分为 2 个 block ，以便进行分页。所以像这样的事情会做:

0 =>
    111 => 
        object(stdClass)[452]
          public 'Description' => string 'Description here...' (length=728)           
          public 'Name' => string 'Shirt' (length=18)
          public 'Price' => float 36.56

    222 => 
        object(stdClass)[452]
          public 'Description' => string 'Description here...' (length=728)           
          public 'Name' => string 'Pants' (length=18)
          public 'Price' => float 36.56
1 =>
    333 => 
        object(stdClass)[452]
          public 'Description' => string 'Description here...' (length=728)           
          public 'Name' => string 'Dress' (length=18)
          public 'Price' => float 36.56

    444 => 
        object(stdClass)[452]
          public 'Description' => string 'Description here...' (length=728)          
          public 'Name' => string 'Dress' (length=18)
          public 'Price' => float 36.56
...

我的问题是通过使用 array_chunk() 将我的对象数组分成 2 组，我的唯一 ID 没有被保留。

private function paginate($array)
{
    $chunks = 2;
    $paginatedResults = array_chunk($array, $chunks);

    return $paginatedResults;
}

函数输出:

0 =>
    0 => 
        object(stdClass)[452]
          public 'Description' => string 'Description here...' (length=728)
          public 'Name' => string 'Shirt' (length=18)
          public 'Price' => float 36.56

    1 => 
        object(stdClass)[452]
          public 'Description' => string 'Description here...' (length=728)
          public 'Name' => string 'Pants' (length=18)
          public 'Price' => float 36.56
1 =>
    0 => 
        object(stdClass)[452]
          public 'Description' => string 'Description here...' (length=728)
          public 'Name' => string 'Dress' (length=18)
          public 'Price' => float 36.56

    1 => 
        object(stdClass)[452]
          public 'Description' => string 'Description here...' (length=728)
          public 'Name' => string 'Dress' (length=18)
          public 'Price' => float 36.56
...

如何将我的键控对象数组拆分为另一个包含每个索引 2 个对象的数组，同时保留包含唯一 ID 的原始数组键？

Answer 1

我所要做的就是将 array_chunk() 的第三个参数设置为 true，如下所示:

$paginatedResults = array_chunk($array, $chunk, true);
