Difference between pluck() and lists() in laravel?
提问by Devashish Jaiswal
This is so confusing to me. I don't see any difference between these two methods. If I var_dump()the object returned by these methods, they are exactly the same but the book by Dayle Rees says that pluck()returns a single value from the given column (the first one) while the lists()method returns all the values from the given column. I can't even figure out why two different methods exist to do the same thing.
这让我很困惑。我看不出这两种方法有什么区别。如果我var_dump()是这些方法返回的对象，它们完全相同，但 Dayle Rees 的书说pluck()从给定列（第一个）返回单个值，而该lists()方法返回给定列中的所有值。我什至无法弄清楚为什么存在两种不同的方法来做同样的事情。
Example
例子
Route::get('getalbum', function() {
$data = \App\Album::pluck('artist');
var_dump($data); // a lot of text, let's call it 'object'
$data = \App\Album::lists('artist');
var_dump($data); // exact , exact, exact same 'object'
});

From the docs, Deprecationssection
从文档，Deprecations部分
The following features are deprecated in 5.2 and will be removed in the 5.3 release in June 2016
The lists method on the Collection, query builder and Eloquent query builder objects has been renamed to pluck. The method signature remains the same.
以下功能在 5.2 中已弃用，并将在 2016 年 6 月的 5.3 版本中删除
集合、查询构建器和 Eloquent 查询构建器对象上的列表方法已重命名为 pluck。方法签名保持不变。
So yes they are same. It's just there for backward compatibility.
所以是的，他们是一样的。它只是为了向后兼容。
