Concatenation with Blade in Laravel

I'm trying to access a table column in my ItemController. In this instance, I wish to use the values in my array + a concatenated string to for the column name.

ItemController.php ....

public function displayItems() {
   $itemsList = array('Alpha','Bravo','Charlie','Delta');
   //$results = returned mysql row here
   return view('items', ['rs' => $results, 'items' => $itemsList]);
}

page.blade.php

@foreach ($items as $item)
  //$item is used elsewhere too, so keep $item
  {{$rs->$item.'_data'}}
@endforeach

Desired output:

$rs->Alpha_data;
$rs->Delta_data;
etc

How can I dynamically set a variable for $rs->name ?

lets say you are retrieving a single record 'task', and this record has variables called 'var1','var2','var3' ... all the way to 'var16'.

you can echo those variables in your blade file like so:

@for($y=1; $y<=16; $y++)
 {{ $task->{'var'.$y} }}
@endfor

Quite simple, just use the . sign for concats in PHP

Try to do this:

{{ $rs->${$item.'_data'} }}
