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

You can use eval(), but it's generally a bad idea, since it's a major potential security hole (be careful you're not allowing visitors to run arbitrary code!).

It can also result in hard to maintain code.
