How is @forelse interpreted in laravel and what is it for?

It is the same as a foreach, but in case the input parameter is empty, it will show what is between @empty and @endforelse .

The goal of @forelse is to reduce the code needed to do:

@if ($users->count())
  @foreach ($users as $user)
    <p>Usuario {{ $user->id }}</p>
  @endforeach
@else
  <p>No hay usuarios.</p>
@endif

to this:

@forelse ($users as $user)
    <p>Usuario {{ $user->id }}</p>
@empty
    <p>No hay usuarios.</p>
@endforelse

With an example it is understood, simply it crosses all the values of the array / collection that you pass to it and if this empty it jumps the else.

@forelse($array as $objeto_individual)
   <h1> {{ $objeto_individual }}</h1>
@empty
   <h1> Sin valores </h1>
@forelse
