Looping through collections -Laravel

问题

I was trying to loop through a collection based on the key

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

How do I loop through this??

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

       dump($results);

Controller

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

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

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

回答2:

foreach($results as $alphabet => $collection) {
  dump($alphabet, $collection);
}
