Example #1

File: Math.php Project: hurcane/tiki-azure

 function handleFinalSave(array $data)
 {
     try {
         $runner = new Math_Formula_Runner(array('Math_Formula_Function_' => ''));
         $runner->setFormula($this->getOption('calculation'));
         $runner->setVariables($data);
         return $runner->evaluate();
     } catch (Math_Formula_Exception $e) {
         return $e->getMessage();
     }
 }
