如何：将 Laravel 集合折叠成逗号分隔的字符串？

dd($ids);

Illuminate\Support\Collection {#538 ▼

  #items: array:463 [▼

    0 => 30578786410269

    1 => 30578326028621

    2 => 30788548304669

    3 => 30788548607437

    4 => 30788592370221

    5 => 30788592672989

    6 => 30788592975757

    7 => 30492511411997

      ]

}

我如何把它变成一个像这样的字符串？：

30578786410269,30578326028621,30788548304669,30788548607437,30788592370221,30788592672989,30788592975757,30492511411997

Answer 1

使用提供的implode方法Illuminate\Support\Collection：$imploded = $collection->implode(',');

Answer 2

您可以使用implode()$data = $collection->implode(',');   // returns string或者您可以转换collection为array$data = $collection->toArray();     // returns array
