How to get array value that get from checkbox input in Laravel's controller?

I want to send 'Date' array from a page to another page through checkbox input for display the data and get more data from database.

I try to dd() the array from input, it's still normal but the data just only show 1 value when I use 'foreach' loop. How do I do?

<input name="isInvoices[]" type="checkbox" value="">

   $invoices = $request->input('isInvoices');
   // dd($invoice); It's show array of date
   foreach($invoices as $invoice) {
      dd($invoice); //It's just only 1 value
   }

I expected the output to show all value in the array, but the actual output is show 1 value.
