遍历集合-Laravel [英] Looping through collections -Laravel

问题描述

我正尝试遍历基于密钥的集合

在这里我要完成的工作是根据我的字母将每个公司分组.

What I am trying to accomplish here is to group each company based on the alphabet in my view.

我该如何循环?

$results = $companies->sortBy('name')->groupBy(function ($item, $key) {
                 return substr($item['name'], 0, 1);
        });

       dump($results);

控制器

推荐答案

作为@msonowal答案的替代方法，您还可以使用

As an alternative to @msonowal's answer you can also use each():

$results->each(function ($collection, $alphabet) {
    dump($alphabet, $collection);
});

但是，如果要在刀片文件中循环浏览它们，则可以使用:

However, if you're going to loop through them in a blade file you would use:

@foreach ($results as $alphabet => $collection)
    {!! dump($alphabet, $collection) !!}
@endforeach
