仅将Laravel集合键合并到字符串中

Question

我有这个Laravel 5.3小巧的系列:

Collection {#325 ?
  #items: array:8 [?
    0 => 2638
    1 => 2100
    2 => 5407
    3 => 2970
    4 => 4481
    5 => 1611
    6 => 5345
    7 => 50
  ]
}

我想要只在字符串中组合值,我需要这个:

"2638,2100,5407,2970,4481,1611,5345,50"

Answer 1

使用implode https://laravel.com/docs/5.3/collections#method-implode

如果$ collection是您显示的值

dd($collection->implode(',')); 应该给出预期的结果

Answer 2

您可以在集合上使用 PHPimplode()或 Laravel->implode()方法：

implode(',', $collection->toArray());

$collection->implode(',');
