| http://www.w3.org/ns/prov#value | - So, for example, once I have parsed "something the result will be a string like: $foo+$bar/$baz;.So, for calculating the result of that expression I am using the eval function... something like this:eval($result = $expresion;);echo The result is: $result;The problem here is that sometimes I get errors that says there was a division by zero, and I do not know how to catch that Exception.
