How can I define variable array on the laravel blade view?

Question

I try like this :

<div class="media-body">
    @foreach($categories as $category)
    @php $category[] = $category->name @endphp
    @endforeach   
    {{ implode(",", $category) }}
</div>

If the code executed, there exist error :

undefine variable category

How can I solve it?

You must define $category[] with different name outside the @foreach loop — blues911

You can simply use Laravel Collection

{{ $categories->pluck('name')->implode(', ') }}

Or if you wanna do this in foreach then

@php ($names = [])

@foreach ($categories as $category)
    @php ($names[] = $category->name)
@endforeach

{{ implode(', ', $names) }}

It does not work. There exist error : Missing argument 2 for Illuminate\Database\Eloquent\Model::setAttribute()...

I try like this :

<div class="media-body">     @php ($category = [])     @foreach($categories as $category)     @php ($category[] = $category->name)     @endforeach        {{ implode(', ', $category) }} </div>

Now it works. Because before variable array = value of foreach. Both names are the same. That's what caused the error. Thanks a lot

You have to declare an array within <?php ... ?> block and then use the same in a {{blade}} block.

Also, there's the Blade special syntax: {{--*/ $var = 'test' /*--}}. Then, you use it in the standard way: {{ $var }}.
