Why the brackets?
It should just be like this
$aspirantes = DB::table('aspirantes')->where('correo_asp',$userCorreo)->first();
The query you are doing only returns an object, not an array, it is not necessary to use a foreach
Now in the view you should place something like the following
<div class="col-md-3">
<div class="form-group row">
<div class="col-sm-12">
@if($aspirantes)
{{ $aspirantes->id_asp }}
@endif
</div>
</div>
</div>
I think they answered the same thing in another question you did.
