php - 如何访问集合中的特定属性？

Question

我想从练习表中访问名称属性，但我得到的是集合。我的代码看起来像。

$practice = Practice::withTrashed()->where('id',$appointment->practice_id)->get();

dd($practice);

结果看起来像

Collection {#697
  #items: array:1 [
    0 => Practice {#698
      #dates: array:1 [
        0 => "deleted_at"
      ]
      #fillable: array:2 [
        0 => "name"
        1 => "email"
      ]
      #connection: null
      #table: null
      #primaryKey: "id"
      #keyType: "int"
      #perPage: 15
      +incrementing: true
      +timestamps: true
      #attributes: array:7 [
        "id" => 42
        "name" => "DJ and Charlie Eye Associates"
        "email" => "vendorsupport@ocuhub.com"
        "created_at" => "0000-00-00 00:00:00"
        "updated_at" => "2017-01-13 06:29:14"
        "liferay_id" => 57238
        "deleted_at" => "2017-01-13 06:29:14"
      ]
      #original: array:7 [
        "id" => 42
        "name" => "DJ and Charlie Eye Associates"
        "email" => "vendorsupport@ocuhub.com"
        "created_at" => "0000-00-00 00:00:00"
        "updated_at" => "2017-01-13 06:29:14"
        "liferay_id" => 57238
        "deleted_at" => "2017-01-13 06:29:14"
      ]
      #relations: []
      #hidden: []
      #visible: []
      #appends: []
      #guarded: array:1 [
        0 => "*"
      ]
      #dateFormat: null
      #casts: []
      #touches: []
      #observables: []
      #with: []
      #morphClass: null
      +exists: true
      +wasRecentlyCreated: false
      #forceDeleting: false
    }
  ]
}

有什么办法可以让我得到“DJ and Charlie Eye Associates”这个名字。我使用了 withThrashed 方法，因为这个条目在练习表中被软删除了。

首先您需要从集合中获取一个对象，然后您可以获取该对象的任何属性:

$practice->first()->name;

或者:

$practice[0]->name;
