Concatenation with Blade in Laravel

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

Try to do this:

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