在@foreach中使用laravel {{}}

If you look at the [documentation] you need to use the @foreach / @endforeach in a similar way as the standard php foreach loop.

在代码中，实际上是将字符串作为循环的参数传递。如果要使其工作，则需要在项目数组上传递条件，然后对其进行循环。

@foreach(($arrayOfProducts->count()/3 == 0) ? $arrayOfProducts : '$arrayOfProducts->chunk(($arrayOfProducts->count()/3))) as $item)

{{ dump($item) }}

@endforeach

您需要学习基本语法。

@foreach($arrayOfProducts as $product)
  {{ $product->someAttr }}
@endforeach

This would work just fine, behind the scenes it's just basic PHP foreach loop, and {{ }} is just echo, also try to keep that conditional logic in your controller for more readable code.
