如何在获取元素后取消设置(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，我想在获取其某些元素时进行迭代和修改.但是我找不到删除该获取的元素的方法或方法.

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);
      }
}

这只是我要演示的问题的代表.

This is just a representation of my question for demonstration.

@Ohgodwhy提出了got()函数的建议后，我再次对其进行了检查，发现我实际上对该函数有误解.正是我想要的.

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，对于有效的解决方案，我在if语句内添加了$collection->forget($key).

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

以下是使用@Ohgodwhy的解决方案来解决我的问题:

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

(这只是一个演示)

推荐答案

您想使用->forget()

$collection->forget($key);
