Variable Operators in PHP

Question

Given this example, how would I return the result of the equation rather than the equation itself as a string?

$operator = \'+\';
foreach($resultSet as $item         


        

Answer 1

Quick answer is eval(). However, in this precise example I would just hard-code the possible operations:

orderField] + 1;
            break;
    }
    echo $result;
}
