String execute as object property in php(laravel)

Question

I want to make dynamic object property from the sting.

$str = '{{$applications->' . str_replace( array('a.','b.','c.','d.'), '', $each_col_array[0]).'}}'
$str = "{{$applicants->applicant_name_en}}" //output

I used this <?php eval($str) ?> for view in blade but gives syntax error, unexpected in
