問題描述
我正在嘗試升級我的項目 L5.1 -> L5.2.在升級指南中，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、查詢構建器和 Eloquent 查詢上的 lists 方法builder 對象已重命名為 pluck.方法簽名保持不變.
The
listsmethod on the Collection, query builder and Eloquent query builder objects has been renamed topluck. The method signature remains the same.
沒關系，將重構從 lists() 重命名為 pluck() 不是問題.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?
來自 5.0 文檔:
從一行中檢索單列
$name = DB::table('users')->where('name', 'John')->pluck('name');
L5.2 中舊的 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) }
推薦答案
pluck() 目前的替代方案是 value().
The current alternative for pluck() is value().
