如何将集合合并到 laravel 中的特定列

Question

我有 3 个不同对象的集合。我需要根据共享值（这里共享值是id）将这3个集合聚合为1个。我的意思是：

$names = {"id":1, "name":"John"};
$ages = {"id":1, "age":20};
$address = "{"id":1, "address":"222"};
  .......
 .........

如果我returnreturn $names->merge($ages)->merge($address)，它会这样显示：

[
  {"id":1, "name":"John"},
  {"id":1, "age":20},
  {"id":1, "address":"222"},
  {"id":2, "name":"Jim"},
  {"id":2, "age":30},
  {"id":2, "address":"333"},
]

我想return这样的我：

[
   {"id":1, "name":"John", "age":20 , "address":"222"},
   {"id":2, "name":"Jim", "age":30 , "address":"333"}
 ]

Answer 1

这是我的解决方案：

$items = [
  {"id":1, "name":"John"},
  {"id":1, "age":20},
  {"id":1, "address":"222"},
  {"id":2, "name":"Jim"},
  {"id":2, "age":30},
  {"id":2, "address":"333"},
];

$items = collect($items)->groupBy('id');
$result = [];
foreach ($items as $values) {
  $temp = [];
  foreach ($values as $value) {
    $temp = array_merge($temp, $value);
  }
  $result[] = $temp;
}

dd($result);
