获取后如何取消设置(删除)集合元素? [英] How to unset (remove) a collection element after fetching it?

问题描述

我有一个集合，我想在获取其中的一些元素时对其进行迭代和修改.但是我找不到删除该获取元素的方法或方法.

I have a collection which I want to iterate and modify while I fetch some of its elements. But I could't find a way or method to remove that fetched element.

$selected = []; 
foreach ($collection as $key => $value) {
      if ($collection->selected == true) {
          $selected[] = $value;
          unset($value);
      }
}

这只是我的演示问题的代表.

This is just a representation of my question for demonstration.

在@Ohgodwhy 建议忘记() 函数后，我再次检查它，发现我实际上误解了该函数.这正是我所寻找的.

After @Ohgodwhy advice the forget() function I checked it again and saw that I actually misunderstood the function. It was exactly as I was looking for.

因此，对于工作解决方案，我在 if 语句中添加了 $collection->forget($key).

So for working solution I have added $collection->forget($key) inside the if statement.

以下是我的问题的有效解决方案，使用@Ohgodwhy 的解决方案:

$selected = []; 
foreach ($collection as $key => $value) {
      if ($collection->selected == true) {
          $selected[] = $value;
          $collection->forget($key);
      }
}

(这只是一个演示)

推荐答案

你可能想要使用 ->forget()

$collection->forget($key);
