You can simply use Laravel Collection
你可以简单地使用 Laravel Collection
{{ $categories->pluck('name')->implode(', ') }}
Or if you wanna do this in foreach then
或者，如果您想在 foreach 中执行此操作，则
@php ($names = [])
@foreach ($categories as $category)
@php ($names[] = $category->name)
@endforeach
{{ implode(', ', $names) }}

You have to declare an array within <?php ... ?>block and then use the same in a {{blade}}block.
您必须在<?php ... ?>块中声明一个数组，然后在块中使用相同的数组{{blade}}。
