循环遍历集合-Laravel

Looping through collections -Laravel(循环遍历集合-Laravel)

问题描述

我试图遍历基于键的集合

我在这里想要完成的是根据我认为的字母表对每个公司进行分组.

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

我如何遍历这个??

$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 答案的替代方案，您还可以使用 each():

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

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

但是，如果您要在刀片文件中遍历它们，您可以使用:

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
