Oh! That's what I searched for. I didn't know how to use eval() function. Thanks for your help! I appreciate. Mart

Thanks, but what if I don't know the content of the string. $str = $_REQUEST['op']; // op si a mathematical operator like +, -, *, / print(2.$str.3); // I want to calculate the result of 2 "operator" 3 I'm not sure that my question is clear enough. But thanks again. Mart.

The output would look like this: [/quote]

I would like to resolve that problem: I have this variable: $str = "2+3"; And I want to print the result of the operation included in that string. How can I do that? Thanks. Mart
