Laravel 5.2 - pluck() 方法返回数组

问题描述

我正在尝试升级我的项目 L5.1 -> L5.2.在升级指南中，我不清楚一件事:

I'm trying to upgrade my project L5.1 -> L5.2. In upgrade guide there's one thing which isn't clear for me:

集合、查询构建器和 Eloquent 查询上的 lists 方法builder 对象已重命名为 pluck.方法签名保持不变.

The lists method on the Collection, query builder and Eloquent query builder objects has been renamed to pluck. The method signature remains the same.

没关系，将重构从 lists() 重命名为 pluck() 不是问题.但是 L5.0 和 L5.1 中有用的 pluck() 方法呢?

That's ok, rename refactoting from lists() to pluck() isn't a problem. But what with useful pluck() method which was in L5.0 and L5.1?

来自 5.0 文档:

从一行中检索单列

$name = DB::table('users')->where('name', 'John')->pluck('name');

L5.2 中旧的 pluck() 方法的替代方法是什么?

What is the alternative for old pluck() method in L5.2?

更新:

示例:

var_dump(DB::table('users')->where('id', 1)->pluck('id'));

L5.1:

// int(1)

L5.2:

// array(1) { [0]=> int(1) }

推荐答案

pluck() 目前的替代方案是 value().

The current alternative for pluck() is value().
