input values with operators in a form

Question

I want to allow users to insert values in a form with operators, as in this example.

60*24

I need to know what is the most appropriate way to process this in php

You can use eval function for that

Something like this once you submit form

echo eval($_POST['yourtextfieldname']);

**NOTICE:** input _must_ be properly checked in this case, because of code injection possibility. It is a simlest way, but **not safest one**. – BlitZ May 07 '13 at 11:33
