将 Laravel Collection 项合并到新数组中

Question

我想合并这 collection 项：

Collection {#1242 ▼
 #items: array:2 [▼
   0 => "1,2,3"
   1 => "4,5,6"
  ]
}

进入这个新数组：

array:6 [▼
  0 => "1"
  1 => "2"
  2 => "3"
  3 => "4"
  4 => "5"
  5 => "6"
]

有什么简单的合并和重新排列的方法吗？谢谢。

Answer 1

我希望这可以用于你的情况

/*
$collection=[
   0 => "1,2,3"
   1 => "4,5,6"
];
* if the above is your collection
*/

$result=[];

$collection->each(function($item)use($result){
    array_push($result, explode(',', $item));
});

dd($result)

Answer 2

您可以使用 Laravel Collection method called map and then just explode each item inside and flatten the result, also using all 到 return 数组，如下所示：

$collection = $collection->map(function ($item) {
     return explode(',', $item);
})->flatten()->all();
